I would like to use a test file to read several objects, but I got a null from step2 to step 4.
For name, if i input Steven, I would like to get ste123 back (123 should be a random number)
Here is the code:
public class Lab14Tester
{
public static void main(String[] args)
{
Introduction step1 = new Introduction();
System.out.println(step1.giveline1());
System.out.println(step1.giveline2());
System.out.println(step1.giveline3());
System.out.println(step1.giveline2());
System.out.println(step1.giveline1());
Scanner in= new Scanner(System.in);
System.out.print("\nName: ");
String inputname = in.nextLine();
Username step2 = new Username();
String givename = step2.givename();
System.out.println("Your username is " + givename);
System.out.print("\nGive me a number: ");
int inputnumber =in.nextInt();
OddEven step3 = new OddEven();
System.out.println(step3.givenumbertype());
System.out.print("\nGive me a number grade: ");
double grade = in.nextDouble();
NumberToLetter step4 = new NumberToLetter();
System.out.printf("\n%.1f", grade);
System.out.print(" is equal to a " + step4.giveletter());
}
}
public class Username
{
private String subname;
private int randomnumber;
private String outputname;
public void getname(String inputname)
{
subname = inputname.substring(0,3);
randomnumber = (int)(Math.random()*1000);
outputname = subname + randomnumber;
}
public String givename()
{
return outputname;
}
}
You could be having trouble because you're concatenating a String with an Integer.
Try this:
public void getname(String inputname)
{
subname = inputname.substring(0,3);
randomnumber = (int)(Math.random()*1000);
String randomnumberAsString = String.valueOf(randomnumber);
outputname = subname + randomnumberAsString;
}

I am trying to utilize the toString() in a class I have called Employee(). I have a 1D array of type Employee, which stores Employee Data, which include the Employee ID, Employee Name, Employee Address, and Employee Hire Date. I want the user to specify the amount of employees, and then enter the relevant data for however many employees the user wants. I then want to print the result for the user with the information entered. I keep getting some results that are null. I tried using an If statement that printed output if it didn't equal null, but that didn't work. I know the output works if I print out a single variable, such as address, but I want all variables to print out. Thank you for any help.

Can someone tell me why my baggage won't print?
For passenger name I enter, say, John.
For country code I enter: BI
For flight number I enter: 095
For number of baggage I can enter any amount.
Let's say I enter: John, BI, 095, 3.
This is what I get: [John with baggage(s) [, , ]] when I should be getting
[John with baggage(s) [BI0950, BI0951, BI0952]]
Sorry if the code is quite messy.
It's amended. Thanks guys.

You're not returning anything in your makeBaggage method, as you can see after the loop it returns the x variable which is not either set inside the loop, in this case your loop is useless.
public static String makeBaggage(String country, String flight, int num){
String x = "";
for(int i = 0; i < num; i++){
String[] bgs = new String[num];
bgs[i] = country + flight + i;
// System.out.println(bgs[i]);
}
return x;
}
I think this is the one you're looking for:
public static String makeBaggage(String country, String flight, int num){
return country + flight + num;
}
For this specific line in your code:
for(int i = 0; i < amount; i++){
String[] bg = new String[amount];
bg[i] = makeBaggage(country, flight, amount);
baggage.add(bg[i]);
System.out.println(bg[i]);
...
Move the String[] bg = new String[amount]; declaration outside of the for loop and instead of supplying the amount in the makeBaggage method, use the loop counter instead as follows: bg[i] = makeBaggage(country, flight, i);
String[] bg = new String[amount];
for(int i = 0; i < amount; i++){
bg[i] = makeBaggage(country, flight, i);
baggage.add(bg[i]);
System.out.println(bg[i])
..
I think that should do it. Also, your code could be greatly improved, and that would be your tasks.

You are trying to print the object without overriding toString you get the default value of classname suffixed with the object's hashcode. You can override your toString as mentioned below.
Another issue is your try to print the entire array instead of the indexed element it currently refers to: System.out.println(gerbil);. You would need to get the indexed element System.out.println(gerbil[i]); (I assume you would want this since you are iterating over the array)
Given that an element in your array exists with ID you provide, take cue from the following toString method (auto-generated through eclipse IDE):
Add this to your Gerbil.java
#Override
public String toString() {
return "Gerbil [idnumber=" + idnumber + ", nickname=" + nickname
+ ", totalfood=" + Arrays.toString(totalfood) + ", foodname="
+ Arrays.toString(foodname) + ", escape=" + escape + ", bite="
+ bite + ", foodeats=" + Arrays.toString(foodeats)
+ ", gerbilsearch=" + gerbilsearch + "]";
}
Change in searchForGerbil()
Replace:
System.out.println(gerbil);
With:
System.out.println(gerbil[i]);
You can try and modify the toString to display the content as you wish to.
In addition to the points PopoFibo made, there's this:
for (int i = 0; i <gerbil.length; i++){
if ( searchgerbil.equals(gerbil[i].getId())){
System.out.println(gerbil);
}
else{
System.out.println("Gerbil " + searchgerbil + " doesnt exist");
}
}
The above code probably does not do what you are hoping for. Say your gerbil array has 10 gerbils, all with different ID's. When you go through the loop, then each time you compare gerbil[i] to the ID, it will display "Gerbil ... doesnt exist" if the ID isn't equal. But this is inside the loop, so that means that if the ID equals one of the array elements, you will get one output line with a gerbil, and 9 output lines that say the gerbil doesn't exist.
You have to move the "doesn't exist" message outside the loop. One way to do that is to declare a new variable boolean found = false before the loop. In the loop, when you find it, set found = true. Then, test found after the loop is done. (You can also use break; once you've found the gerbil inside the loop, because that probably means you can stop searching.)
Each time I run this code it gets to where it asks for student id and it prints out the student id part and the homework part. Why? I am trying to do get a string for name, id, homework, lab, exam, discussion, and project then in another class I am splitting the homework, lab, and exam strings into arrays then parsing those arrays into doubles. After I parse them I total them in another method and add the totals with project and discussion to get a total score.

while ( test = true)
You probably want to change that to

Also, take these lines out of the loop:
Scanner keyboard = new Scanner(System.in);
PrintWriter outputFile = new PrintWriter("gradeReport.txt");
In addition to Ermir's answer, this line won't capture all the grades:
System.out.println("Please enter the 10 homework grades seperated by a space: ");
String homework = keyboard.next();
Keyboard.next only reads until the next delimiter token, so if you want to capture 10 grades separated by spaces you need capture the whole line, like:
System.out.println("Please enter the 10 homework grades separated by a space: ");
String homework = keyboard.nextLine();
I am a first year student and learning setter and getter at school.
When I run it, it is ignoring the following statement:
String Origin = scan.nextLine();
and then it goes to the next line.
Here is the main:
import java.util.Scanner;
public class FlightTest
{
public static void main (String [] args)
{
Scanner scan = new Scanner (System.in);
Flight Flight1 = new Flight ();
System.out.print ("Airline Name: ");
String AirlineName = scan.nextLine ();
System.out.print ("Flight Number: ");
int FlightNumber = scan.nextInt ();
System.out.print ("Origin: ");
String Origin = scan.nextLine(); // There is a problem here
System.out.print ("Destination: ");
String Destination = scan.nextLine ();
}
}
This is the class
public class Flight
{
private String AirlineName;
private int FlightNumber;
private String Origin;
private String Destination;
public String setAirlineName()
{
String Name = AirlineName;
return Name;
}
public String getAirlineName()
{
return AirlineName;
}
public int setFlightNumber ()
{
int Number = FlightNumber;
return Number;
}
public int getFlightNumber ()
{
return FlightNumber;
}
public String setOrigin ()
{
String Orig = Origin;
return Orig;
}
public String getOrigin ()
{
return Origin;
}
public String setDestination ()
{
String Desti = Destination;
return Desti;
}
public String getDestination ()
{
return Destination;
}
public String toString ()
{
String result = AirlineName + " flight number "
+ FlightNumber + " leaves from " + Origin + " to "
+ Destination + ".";
return result;
}
}
because scan.nextInt() doesn't use the whole line, the next call to scan.nextLine() is returning the end of the line that the flight number was on, which is probably just a newline.
Add another call to scan.nextLine()
System.out.print ("Flight Number: ");
int FlightNumber = scan.nextInt ();
scan.nextLine(); // get rid of rest of line
System.out.print ("Origin: ");
String Origin = scan.nextLine();
and I think things will work.
and your setter is wrong, you should pass a parameter.
private String airlineName;
public String getAirlineName() {
return airlineName;
}
public void setAirlineName(String airlineName) {
this.airlineName = airlineName;
}
you can use setter like this
Flight f = new Flight ();
System.out.print ("Airline Name: ");
f.setAirlineName(scan.nextLine ());
