Gson.fromJson(json, Custom.class) empty string

i'm developing a small web application.
That's my problem:
This is executed when a user try to add a new record in my Datatable
#RequestMapping(value="/saveJokerRule", method= RequestMethod.POST, consumes= "application/json", produces = "application/json")
#ResponseBody
public String saveJokerRule(#RequestBody String json) {
System.out.println("JSON EDITOR:" + json.toString());
EditorResponse editorResponse = new EditorResponse();
JokerRuleForm jokerRuleForm = new GsonBuilder().serializeNulls().create().fromJson(json, JokerRuleForm.class);
...
}
This is the valid json received by the server and printed by a System call:
{"action":"create","data":{"0":{"jokerRule":{"group":1,"campaignPhase":"","dailyLimit":"","weeklyLimit":"","monthlyLimit":"","validFrom":"","activity":1}}}}
That's the JokerRuleForm classs
public class JokerRuleForm {
#Expose
String action;
#Expose
#SerializedName("data")
Map<String, JokerRuleView> data;
...
}
That's the JokerRuleView class
public class JokerRuleView {

When executing this line i got a NumberFormatException empty string and i think it dailyLimit's or date's fault because it's empty and fromJson() method can't do what he need to do.
I've read something about a TypeAdapter that seems can fit to my case, but i don't really know how to proceed and i'm not sure is a valid solution.
Can someone help me?

The limit fields e.g. dailyLimit are empty strings in your JSON. This was suggested in JsonParseException when encountering an empty value for an int or long #472 issue but Gson team closed it because it makes no sense to parse "" as int.
One of the users provided a solution in his comment which allows to leniently parse the number values. I'd not go this route myself and fix JSON instead, but it's up to you:
public static final TypeAdapter<Number> UNRELIABLE_INTEGER = new TypeAdapter<Number>() {
#Override
public Number read(JsonReader in) throws IOException {
JsonToken jsonToken = in.peek();
switch (jsonToken) {
case NUMBER:
case STRING:
String s = in.nextString();
try {
return Integer.parseInt(s);
} catch (NumberFormatException ignored) {
}
try {
return (int)Double.parseDouble(s);
} catch (NumberFormatException ignored) {
}
return null;
case NULL:
in.nextNull();
return null;
case BOOLEAN:
in.nextBoolean();
return null;
default:
throw new JsonSyntaxException("Expecting number, got: " + jsonToken);
}
}
#Override
public void write(JsonWriter out, Number value) throws IOException {
out.value(value);
}
};
public static final TypeAdapterFactory UNRELIABLE_INTEGER_FACTORY = TypeAdapters.newFactory(int.class, Integer.class, UNRELIABLE_INTEGER);
Gson gson = new GsonBuilder()
.registerTypeAdapterFactory(UNRELIABLE_INTEGER_FACTORY)
.create();

I am using spring form tags to create registration form and added code as follows
<label>
<form:checkbox path="personalDetails.isPresentAddressSame" />
Present address same as above
</label>
As I have a variable personalDetails and it has a field isPresentAddressSame it should match the getter setter but I am getting following error
There was an unexpected error (type=Internal Server Error, status=500).
Invalid property 'personalDetails.isPresentAddressSame' of bean class [com.hr.foundation.models.doc.models.employee.Employee]: Bean property 'personalDetails.isPresentAddressSame' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
Other fields with type String are matching with the path like personalDetails.firstName but not this Boolean field

You did not include the getter/setters of the PersonalDetails class, but Spring says that's where the error is.
Make sure you have these:
boolean isPresentAddressSame() { ... }
and
void setPresentAddressSame(boolean value) { ... }
Your mistake is likely that either:
You used a Boolean in either the parameter or return type (note the capital B)
You used getPresentAddressame which is only allowed for Boolean (note capital B again) instead of isPresentAddressSame which you should use for boolean (small B).
Clarification
Change:
public Boolean isPresentAddressSame() {
return isPresentAddressSame;
}
public void setPresentAddressSame(Boolean isPresentAddressSame) {
if (isPresentAddressSame) {
presentAddress = permanentAddress;
}
this.isPresentAddressSame = isPresentAddressSame;
}
to:
public boolean isPresentAddressSame() {
return isPresentAddressSame;
}
public void setPresentAddressSame(boolean isPresentAddressSame) {
if (isPresentAddressSame) {
presentAddress = permanentAddress;
}
this.isPresentAddressSame = isPresentAddressSame;
}
Note again that the boolean here uses a small b.

Try to change the signature of the method:
public Boolean isPresentAddressSame() {
return isPresentAddressSame;
}
to
public Boolean getPresentAddressSame() {
return isPresentAddressSame;
}
if you are using spring, spring alwais looking for get word to resolve the beans properties.

Creating an array with 3 variables

I am trying to create an array of students which will contain 3 different types of students and each of the students will have 3 variables name, and 2 grades.
This is what I have done so far, and it gives me the following error cannot find symbol.
Main class:
public class JavaLab5 {
public static final int DEBUG = 0;
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
Student s[] = new Student[10];
s[0] = new MathStudent(Smith,14,15);
s[1] = new MathStudent(Jack,16,19);
s[2] = new MathStudent(Victor,18,21);
s[3] = new MathStudent(Mike,23,28);
s[4] = new ScienceStudent(Dave,32,25);
s[5] = new ScienceStudent(Oscar,28,56);
s[6] = new ScienceStudent(Peter,29,28);
s[7] = new ComputerStudent(Philip,25,38);
s[8] = new ComputerStudent(Shaun,34,39);
s[9] = new ComputerStudent(Scott,45,56);
for (int loop = 0; loop < 10; loop++) {
System.out.println(s[loop].getSubjects());
System.out.print(loop + " >>" + s[loop]);
}
}
}
This is the Student class:
public class Student {
private String name;
//private int age;
//public String gender = "na";
public static int instances = 0;
// Getters
//public int getAge() {
//return this.age;
//}
public String getName() {
return this.name;
}
// Setters
//public void setAge(int age) {
//this.age = age;
//}
public void setName(String name) {
if (JavaLab5.DEBUG > 3) System.out.println("In Student.setName. Name = "+ name);
this.name = name;
}
/**
* Default constructor. Populates name,age and gender
* with defaults
*/
public Student() {
instances++;
//this.age = 18;
this.name = "Not Set";
//this.gender = "Not Set";
}
/**
* Constructor with parameters
* #param age integer
* #param name String with the name
*/
public Student(String name) {
//this.age = age;
this.name = name;
}
/**
* Gender constructor
* #param gender
*/
//public Student(String gender) {
//this(); // Must be the first line!
//this.gender = gender;
//}
/**
* Destructor
* #throws Throwable
*/
protected void finalize() throws Throwable {
//do finalization here
instances--;
super.finalize(); //not necessary if extending Object.
}
public String toString () {
return "Name: " + this.name; //+ " Age: " + this.age + " Gender: "
//+ this.gender;
}
public String getSubjects() {
return this.getSubjects();
}
}
and this is the MathStudent class which inherits from the Student class:
public class MathStudent extends Student {
private float algebraGrade;
private float calculusGrade;
/**
* Default constructor
* #param name
* #param algebraGrade
* #param calculusGrade
*/
public MathStudent(String name, float algebraGrade, float calculusGrade) {
super();
this.algebraGrade = algebraGrade;
this.calculusGrade = calculusGrade;
}
public MathStudent() {
super();
algebraGrade = 6;
calculusGrade = 4;
}
// Getters
public void setAlgebraGrade(float algebraGrade){
this.algebraGrade = algebraGrade;
}
public void setCalculusGrade(float calculusGrade){
this.calculusGrade = calculusGrade;
}
// Setters
public float getAlgebraGrade() {
return this.algebraGrade;
}
public float getCalculusGrade() {
return this.calculusGrade;
}
/**
* Display information about the subject
* #return
*/
#Override
public String getSubjects(){
return(" Math Student >> " + "Algebra Grade: " + algebraGrade
+ " Calculus Grade: " + calculusGrade);
}
}

Check how you instantiate students, i.e.
new MathStudent(Smith,14,15);
The name should be in quotes like "Smith"
new MathStudent("Smith",14,15);
Otherwise Smith will be interpreted as variable and this one is not defined.

How do you create an access method to convert a string to a boolean

How do you create an access method to convert a string to a boolean?
current access method below
protected boolean fullTime;
/**
* Get the value of fullTime
*
* #return the value of fullTime
*/
public boolean isFullTime() {
return fullTime;
}
/**
* Set the value of fullTime
*
* #param fullTime new value of fullTime
*/
public void setFullTime(boolean fullTime) {
this.fullTime = fullTime;
}
Can it be done similar to this below
/**
* set the coaches names
* #param coaches as an array of strings
*/
public void setCoaches(String coaches)
{
this.coaches = getStringAsArray(coaches);
}
public String getCoachesAsString()
{
return getArrayAsString(coaches);
}

Like this?
protected boolean fullTime;
public String getFullTimeAsString(){
return Boolean.toString(fullTime);
}
public void setFullTimeAsString(String fulltimeStr){
fullTime = "true".equalsIgnoreCase(fulltimeStr);
}
EDITED:
private static final String YES = "yes";
private static final String NO = "no";
protected boolean fullTime;
public String isFullTimeAsString() {
return fullTime? YES: NO;
}
public void setFullTime(String fullTime) {
this.fullTime =YES.equalsIgnoreCase(fullTime);
}

Is this what you wanted?
protected boolean fullTime;
public String isFullTimeAsString() {
return String.valueOf(fullTime);
}
public void setFullTime(String fullTime) {
this.fullTime = Boolean.parseBoolean(fullTime);
}

Is there something simple and probably obvious I'm missing?
Yes - you haven't overridden toString in TriviaQuestion, so you're getting the default implementation from Object:
The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `#', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + '#' + Integer.toHexString(hashCode())
Just add this to TriviaQuestion:
#Override public String toString() {
return "Player: " + player + "; Category: " + category
+ "; Question: " + question + "; Answer: " + answer
+ "; Score: " + score;
}
(Or use String.format within the method to do the same kind of thing.)

You need to override the toString method in your TriviaQuestion class to print the objects in the way you want to. The defualt implementation of toString method prints the memory representation of object.
Note: If you don't know how to write toString method, then make use of some IDE such as eclipse to generate the toString method for you. In eclipse,
go to your class in the editor, right click-> source - > generate
toString.
