Value of variable not updating in Java NetBeans
I have two java files in same package. I want to take the updated value of one variable from one file to another. I wrote the following code. In class1.java :-
import javax.swing.JOptionPane; public class class1 { public static String bar = "Yes"; static int age = 26; public static void main(String[] args){ switch(age) { case 25: bar = "world"; break; case 26: bar = "good"; break; case 27: bar = "very"; break; case 30: bar = "hello"; break; default: JOptionPane.showMessageDialog(null,"Please"); break; } } } In class2.java :-
public class class2 { public static void main(String[] args){ class1 second = new class1(); System.out.println(second.bar); } } The problem is that the final value is printed Yes which should not be printed. The output should be good. Please help me.
You create a class1 object, but you never run the main method. This means that the section of code never runs, and thus bar remains as "Yes".
In class2 insert second.main(args); before you print second.bar and you will get a good value.
class class1 { public String getBar(String age){ String bar = "Yes"; switch(Integer.valueOf(age)) { case 25: bar = "world"; break; case 26: bar = "good"; break; case 27: bar = "very"; break; case 30: bar = "hello"; break; } return bar; } } public class class2 { public static void main(String[] args){ String age = JOptionPane.showInputDialog("Age Please"); class1 class1Obj = new class1(); System.out.println(class1Obj.getBar(age)); } }
