Question

Given the following program, what is the output? It must be in the correct order! Figure it out by hand rather than by coding it!

public class Scope {

    int x = 1;  
    static int y = 2;

    public Scope() {
        int x = 5;

        System.out.println("x in Scope(1): " + x);

        a();
        b();
        a();
        b();

        System.out.println("x in Scope(2): " + x);
    }

   

    void a() {
        int x = 25;
        System.out.println("x in a(1): " + x);

        ++x;
        System.out.println("x in a(2): " + x);
    }

   

    void b() {
        System.out.println("x in b(1): " + x);

        x *= 10;
        System.out.println("x in b(2) " + x);
    }

  

    public static void main(String[] args) {
        Scope s = new Scope();

        System.out.println("y in main(1) " + y);   

        System.out.println("y in main(2) " + s.y);    }
}

Explanation / Answer

x in Scope(1): 5     //constructor of the scope is called
x in a(1): 25       // inside a() method ,local variable got the highest priority so x =25
x in a(2): 26      // inside a() method, increase the x by preincrement operator "++x" so x=26
x in b(1): 1       // inside b() method , it is using the instance variable x so value will be 1

x in b(2) 10     // inside b() method, multiplying x with 10 so value will be 10
x in a(1): 25   // inside a() method // inside a method ,local variable got the highest priority so x =25
x in a(2): 26      // inside a() method, increase the x by preincrement operator "++x" so x=26

x in b(1): 10 // inside b() method ,it is using the instance variable...previously the value was 10 so the present value will be 10
x in b(2) 100 // inside b() method,multiplying with 10 so value will be 100
x in Scope(2): 5 //inside class a, sysout will be called
y in main(1) 2 //main() method, main method sysout will be called
y in main(2) 2 //main() method,main method sysout will be called
