Switch while loop

I have a basic method that implements controlling of application menu using switch
public void applicationMenu(String input) {
switch (input) {
case "1":
findGroups();
break;
case "2":
findStudentsByCourseName();
break;
case "3":
addNewStudent();
break;
case "4":
deleteStudentById();
break;
case "5":
addStudentToCourse();
break;
case "6":
removeStudentCourse();
break;
default:
printDefault();
break;
}
}
I use this method with a while loop to call my application menu
public void callMenu() {
boolean exit = false;
while (!exit) {
viewProvider.printMainMenu();
String input = viewProvider.readString();
if (input.equals("7")) {
exit = true;
}
applicationMenu(input);
}
}
How can I trigger exit from switch case but keep the structure of two methods at the same time?

This should work:
public boolean applicationMenu(String input) {
boolean shouldContinue = true;
switch (input) {
case "1":
findGroups();
break;
case "2":
findStudentsByCourseName();
break;
case "3":
addNewStudent();
break;
case "4":
deleteStudentById();
break;
case "5":
addStudentToCourse();
break;
case "6":
removeStudentCourse();
break;
case "7":
shouldContinue = false;
break;
default:
printDefault();
break;
}
return shouldContinue;
}
...
public void callMenu() {
while (true) {
viewProvider.printMainMenu();
String input = viewProvider.readString();
if (!applicationMenu(input)) {
break;
}
}
}

As stated in comments, you could throw an Exception, but I typically don't like to do that if i'm not in an actual error state. It makes more sense to me to use a return value and evaluate the result to determine if the program should terminate:
public void callMenu() {
boolean exit = false;
while (!exit) {
viewProvider.printMainMenu();
exit = applicationMenu(viewProvider.readString());
}
}
public boolean applicationMenu(String input) {
switch (input) {
case "1":
findGroups();
return false;
case "2":
findStudentsByCourseName();
return false;
case "3":
addNewStudent();
return false;
case "4":
deleteStudentById();
return false;
case "5":
addStudentToCourse();
return false;
case "6":
removeStudentCourse();
return false;
case "7":
return true;
default:
printDefault();
}
return false;
}

Calling a method to return a different int from a switch

I'm trying to call a method and based on the input, return that value to a switch I have in another class. So if I were to choose the "1" element in my array, I would get reply returned as "4" back into my other class and make it run switch "4".
In the other class I have the switch "4" set to another method. However, I keep getting the int value "1" returned from my method as it keeps calling that method (switch "1"). Which makes sense since it's the "1" element in my array, it should then run switch "1", but I thought that by setting "reply = 4", it would return an int "4" into my other class and thus invoke switch "4".
How do I get my methods to return the value I want so I can put into my switch?
Here's my first class where I'm doing the calling:
package bunnyhunt;
import javax.swing.ImageIcon;
import javax.swing.JOptionPane;
public class Messages {
//Objects
public Rooms roomCall = new Rooms();
//Instance Variables
public static boolean gameOver = false;
public static int roomNum;
public static int reply;
boolean visitedOtherRoom = false;
//Constructors
//Methods
public void start() {
//while loop
while (gameOver == false) {
//do-while loop
do {
String[] parkEntrance = {"Spring Meadow", "Aeryn's Overlook", "Garden Gate"};
reply = JOptionPane.showOptionDialog(null, "You're at the Park Entrance! What do you want to do?", "Bunny Adventure", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, parkEntrance, parkEntrance[0]);
switch (reply) {
case 0:
System.out.println("oh man...Spring");
visitedOtherRoom = true;
roomCall.springMeadow();
break;
case 1:
System.out.println("oh man...Aeryn");
visitedOtherRoom = true;
roomCall.aerynsOverlook();
break;
case 2:
System.out.println("oh man...Garden");
visitedOtherRoom = true;
roomCall.gardenGate();
break;
default:
System.out.println("error");
}
} while (visitedOtherRoom == false);
switch (reply) {
case 0:
System.out.println("second 0!!!");
visitedOtherRoom = true;
roomCall.parkEntrance();
break;
case 1:
visitedOtherRoom = true;
System.out.println("yes man!");
roomCall.aerynsOverlook();
break;
case 2:
visitedOtherRoom = true;
roomCall.gardenGate();
break;
case 3:
visitedOtherRoom = true;
roomCall.peacefulPond();
break;
case 4:
visitedOtherRoom = true;
roomCall.readingNook();
break;
default:
System.out.println("default");
}
}
JOptionPane.showMessageDialog(null,
"Game Over!!!");
}
}
and my second where the things I call reside:
package bunnyhunt;
import javax.swing.JOptionPane;
public class Rooms {
public static int reply;
public int springMeadow() {
String[] springMeadow = {"Park Entrance", "Reading Nook", "Search"};
Messages.reply = JOptionPane.showOptionDialog(null, "You're in the Spring Meadow! What do you want to do?", "Spring Meadow", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, springMeadow, springMeadow[0]);
switch (reply) {
case 0:
reply = 0;
break;
case 1:
reply = 4;
break;
case 2:
JOptionPane.showMessageDialog(null,
"You searched!");
break;
default:
System.out.println("error");
}
return reply;
}
public int aerynsOverlook() {
String[] aerynsOverlook = {"Park Entrance", "Peaceful Pond", "Search"};
Messages.reply = JOptionPane.showOptionDialog(null, "You're in Aeryn's Overlook! What do you want to do?", "Aeryn's Overlook", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, aerynsOverlook, aerynsOverlook[0]);
return reply;
}
public int gardenGate() {
String[] gardenGate = {"Park Entrance", "Rose Gardent", "Butterfly Garden", "Flowering Forest"};
return reply;
}
public int readingNook() {
String[] readingNook = {"Spring Meadow", "Search"};
Messages.reply = JOptionPane.showOptionDialog(null, "You're in the Reading Nook! What do you want to do?", "Reading Nook", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, readingNook, readingNook[0]);
return reply;
}
public int parkEntrance() {
String[] parkEntrance = {"Spring Meadow", "Aeryn's Overlook", "Search"};
Messages.reply = JOptionPane.showOptionDialog(null, "You're in the Park Entrance! What do you want to do?", "Park Entrance", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, parkEntrance, parkEntrance[0]);
return reply;
}
public int peacefulPond() {
String[] peacefulPond = {"Raven's Tower", "Aeryn's Overlook", "Search"};
Messages.reply = JOptionPane.showOptionDialog(null, "You're in the Peaceful Pond! What do you want to do?", "Peaceful Pond", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, peacefulPond, peacefulPond[0]);
return reply;
}
}

You are not returning a reply value from the start() method since this method is void AND switch statements inside don't return anything, despite they contain calls to appropriate methods like int aerynsOverlook(). You should modifystart` method like this:
public int start() {
...
switch (reply) {
case 0:
System.out.println("oh man...Spring");
visitedOtherRoom = true;
return roomCall.springMeadow();
...
Secondly, I don't see how you are calling start() method to get its return value and use it in the second switch. Your MEssages class doesn't have any connection with the Rooms

Error Parsing XML response attributes with ksoap2 returns ClassCastException

I'm trying to figure out how to cast the response of the consume of a webservice, when casting the response envelope.bodyIn to my extended class object "BiometricConfigurationResponse" i'm getting this error:
java.lang.ClassCastException: org.ksoap2.serialization.SoapObject cannot be cast to org.tempuri.BiometricConfigurationResponse
The service is responding well and if i not cast it i get the dump right.
Any ideas?
This is what i'm doing:
BiometricConfigurationResponse response= null;
SoapObject obj = new SoapObject (wsNameSpace, methodName);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.implicitTypes = true;
envelope.dotNet = true;
envelope.setOutputSoapObject(obj);
envelope.addMapping(wsNameSpace, "BiometricConfigurationResponse", new BiometricConfigurationResponse().getClass());
HttpTransportSE androidHttpTransport = new HttpTransportSE(wsURL);
androidHttpTransport.debug = true;
try {
String soapAction=wsNameSpace + methodName;
androidHttpTransport.call(soapAction, envelope);
System.out.println(androidHttpTransport.requestDump);
response = (BiometricConfigurationResponse)envelope.bodyIn;
}
catch (Exception e) {
e.printStackTrace();
}
And this is my custom class

After several days of research i understood that WSDL autogenerated code parse Properties but not Atrributes. So what i did was this:
First i generate the stub code from my WSDL in this website: http://www.wsdl2code.com/pages/home.aspx
My webservice name is "nutriment" son when you call it in MainActivity you have to do this:
nutriment nws= new nutriment();
BiometricConfigurationResponse respuesta = nws.GetBiometricConfiguration();
Log.i(TAG, String.valueOf(respuesta.coderAlgorithm));
Log.i(TAG, String.valueOf(respuesta.templateFormat));
But it responses 0 in all cases because the WDSL stub files are parsing PROPERTIES NOT ATRIBUTES, so when you open the serialization generated file you'll got something like this:
import org.ksoap2.serialization.KvmSerializable;
import org.ksoap2.serialization.PropertyInfo;
import java.util.Hashtable;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
public class BiometricConfigurationResponse implements KvmSerializable {
public int coderAlgorithm;
public int templateFormat;
public BiometricConfigurationResponse(){}
public BiometricConfigurationResponse(SoapObject soapObject)
{
if (soapObject == null)
return;
if (soapObject.hasProperty("coderAlgorithm"))
{
Object obj = soapObject.getProperty("coderAlgorithm");
if (obj != null && obj.getClass().equals(SoapObject.class)){
SoapPrimitive j =(SoapPrimitive) obj;
coderAlgorithm = Integer.parseInt(j.toString());
}
else if (obj!= null && obj instanceof Number){
coderAlgorithm = (Integer) obj;
}
}
if (soapObject.hasProperty("templateFormat"))
{
Object obj = soapObject.getProperty("templateFormat");
if (obj != null && obj.getClass().equals(SoapPrimitive.class)){
SoapPrimitive j =(SoapPrimitive) obj;
templateFormat = Integer.parseInt(j.toString());
}else if (obj!= null && obj instanceof Number){
templateFormat = (Integer) obj;
}
}
}
#Override
public Object getProperty(int arg0) {
switch(arg0){
case 0:
return coderAlgorithm;
case 1:
return templateFormat;
}
return null;
}
#Override
public int getPropertyCount() {
return 15;
}
#Override
public void getPropertyInfo(int index, #SuppressWarnings("rawtypes") Hashtable arg1, PropertyInfo info) {
switch(index){
case 0:
info.type = PropertyInfo.INTEGER_CLASS;
info.name = "coderAlgorithm";
break;
case 1:
info.type = PropertyInfo.INTEGER_CLASS;
info.name = "templateFormat";
break;
}
#Override
public void setProperty(int arg0, Object arg1) {
}
#Override
public String getInnerText() {
// TODO Auto-generated method stub
return null;
}
#Override
public void setInnerText(String arg0) {
// TODO Auto-generated method stub
}
}
The trick is to modify the parsing so instead of get the properties(e.g.):
if (soapObject.hasProperty("coderAlgorithm")){
Object obj = soapObject.getProperty("coderAlgorithm");
if (obj != null && obj.getClass().equals(SoapObject.class)){
SoapPrimitive j =(SoapPrimitive) obj;
coderAlgorithm = Integer.parseInt(j.toString());
}
else if (obj!= null && obj instanceof Number){
coderAlgorithm = (Integer) obj;
}
}
Get the ATTRIBUTES (e.g.):
if (soapObject.hasAttribute("coderAlgorithm")) {
Object obj = soapObject.getAttribute("coderAlgorithm");
if (obj != null && obj.getClass().equals(SoapObject.class)){
SoapPrimitive j =(SoapPrimitive) obj;
coderAlgorithm = Integer.parseInt(j.toString());
}
else if (obj!= null && obj instanceof Number){
coderAlgorithm = (Integer) obj;
}
else if (obj!= null && obj instanceof String){
coderAlgorithm = Integer.parseInt(obj.toString());
}
}

The variables such as uaero and uagri are boolean fields of objects. I have a quite a few objects in this class. The variables such as ListOfMajors.aerospace and ListOfMajors.agricultural are boolean values from another class which are set to true if a checkbox is clicked. All of these pairs of variables correspond with each other and would like the variable match set to true if both of the other variables are true. As of right now, the code doesn't seem to working as match doesn't appear to be changing to true. What should I do to get this to work?

Your cases are probably not doing what you think .. since there is no break a case position 0 will set all of the variables to true (or false)
switch(position){
case 0: aerospace = true; break;
case 1: agricultural = true;break;
case 2: biomed = true;break;
case 3: chem = true;break;
case 4: civil = true;break;
case 5: computer = true;break;
case 6: electrical = true;break;
case 7: physics = true;break;
case 8: environment = true;break;
case 9: industrial = true;break;
case 10: materials = true;break;
case 11: mechanical = true; break;

You are missing a break statement after case 1 and case 2 :
expListView.setOnChildClickListener(new OnChildClickListener() {
#Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
switch(groupPosition) {
case 1:
switch (childPosition) {
case 0:
Intent c1= new Intent(MainActivity.this,Webv1Activity.class);
startActivity(c1);
break;
}

case 2:
switch (childPosition) {
case 0:
Intent d1= new Intent(MainActivity.this,Webv1Activity.class);
startActivity(d1);
break;

startActivity(d2);
break;
