Hi,

WHY in the following dode,thread does not exits ,when we call interrupt on it?

class A extends Thread { public void run() { System.out.println("Starting loop"); while(true){} } } public class TestClass { public static void main(String args[]) throws Exception { A a = new A(); a.start(); Thread.sleep(1000); a.interrupt(); } }

Hi,

Is this stmt is true?

You can directly run the garbage collector whenever you want to and it will be schedule in due time..

Thanks

Hi,

Why the following code is not giving compile time error
public class Test2{ static void method(Object obj){ System.out.println("Object"); } static void method(String str){ System.out.println("String"); } public static void main(String args[]){ method(null); } }

Thanks

Hi,

Can you please explain this code
interface I { int i = 1, ii = Test112.out("ii", 2); } interface J extends I { int j = Test112.out("j", 3), jj = Test112.out("jj", 4); } interface K extends J { int k = Test112.out("k", 5); } class Test112 { public static void main(String[] args) { System.out.println(K.j); } public static int out(String s, int i) { System.out.println(s + "=" + i); return i; } }

I think,in interface the variables must be initialized at thier declaration.But here the code is containing method calls.And also iam not able to understand the output.

Please Help Me

Hi,
Why the following program is compiling.The overriding method must not change the return types.then why so?

class A { int x = 5; } class B extends A { int x = 6; } public class CovariantTest { public A getObject() { System.out.println("In A"); return new A(); } public static void main(String[] args) { CovariantTest c = new SubCovariantTest(); System.out.println(c.getObject().x); } } class SubCovariantTest extends CovariantTest { public B getObject() { System.out.println("In B"); return new B(); } }
