Question

What is the output of the following?

Program 1

// filename Main.java
class Test {
protected int x, y;
}

class Main {
public static void main(String args[]) {
Test t = new Test();
System.out.println(t.x + " " + t.y);
}
}

Answer 1

The output of the given program is "0 0".

Step-by-step explanation:

The output of the given program is "0 0".

This is because the class Test has two integer variables, x and y, which are by default initialized to 0. In the main method, a new object of the Test class is created and assigned to the variable t. Since no values are assigned to x and y, they retain their default values of 0.

When we print t.x and t.y using System.out.println, it will display "0 0".

The Main.java program defines a class Test with two protected integer variables x and y. Since these variables are not initialized to any value, they will take the default value for integers in Java, which is 0. Therefore, when an object of class Test is created and we print the variables x and y, the output will display 0 0, which represents the default values of these two variables.
