Practice Questions (3)
What happens when we try to run the following? class J { public J(String x) { } } class K { public K() { } } public class L { public static void main(String[] args) { K k = new K(); } }
What output do we get if we run the following code? class X { private int a; private int y; public X() { this.a = 5; } public X(int y) { this(); this.y = y; System.out.print(a); System.out.print(this.y); } } public class Z { public static void main(String[] args) { X x = new X(3); } }
Does the following code compile successfully? ```java class X { private int a; private int y; public X() { this.a = 10; } public X(int y) { this(); this.y = y * 10; System.out.print(this.a + " "); System.out.print(this.y + " "); } } public class Z { public static void main(String[] args) { X x = new X(5); } } ```
