Switch Question

[FAM]

Im very inexperienced with Java but is it possible to have a switch statement which when you enter the number of your choice (ie from a JOptionPane.showInputDialog) it calls up/runs a set of code?
ie public double getBalance(){

Thanks in advance

sure, if your switch statements take values up to int only (that includes byte, char, and short as well). Anything beyond, long to double will result in compilation errors.

public class SwitchDemo {
public static void main(String[] args) {

int month = 8;
switch (month) {
case 1: System.out.println("January" break;
case 2: System.out.println("February" break;
case 3: System.out.println("March" break;
case 4: System.out.println("April" break;
case 5: System.out.println("May" break;
case 6: System.out.println("June" break;
case 7: System.out.println("July" break;
case 8: System.out.println("August" break;
case 9: System.out.println("September" break;
case 10: System.out.println("October" break;
case 11: System.out.println("November" break;
case 12: System.out.println("December" break;
}
}
}

yes! you can. here ia a sample code.

switch(Integer.parseInt(<JOptionPane.showInputDialog>)){
case 1:<object referenece>.balance();
default:;
}

make sure that you enter only integer value when prompted for input.
