Which class is the immediate superclass of the Container class?

class test{} class tester extends test{ public static void main(String[] args) { test t1 = new tester(); test t2 = new test(); tester t3 = new tester(); System.out.println( t1 instanceof tester); System.out.println( t2 instanceof tester); System.out.println( t3 instanceof tester); System.out.println( t1 instanceof test); System.out.println( t2 instanceof test); System.out.println( t3 instanceof test); }

public class Fun { public static void main(String[] args){ int x=0; boolean b=true; String str; str=(b)?"success": (x=0)?"Failure":"Neither"; System.out.println(str); } }

class Root { int bark=10; public void get(){ System.out.println("Root"); } } public class Tree extends Root{ public void get(){ bark =15; System.out.println("Tree"); } public static void main(String[] args){ Tree t = new Tree(); Root r = new Root(); Root t1= new Tree(); r.get(); t.get(); t1.get(); System.out.println(t.bark); System.out.println(t1.bark); System.out.println(r.bark); } }

public class Top { private int i; Top(int i) {this.i=i; } public int getValue(){ return this.i; } } class Bottom{ public static void main(String[] args) { Top tp = new Top(5); String j = Integer.toString(tr.getValue()); tp.i=15; System.out.println( tp.i + j); } }

public class Play { public static void main(String[] args) { int[][] a = {{5,2,4,7}, {9,2}, {3,4}}; int[] b = a[1]; int[][] b1= new int[3][]; int a2 = b[2]; System.out.println(a2); } }

What is the output of following block of program ? boolean var = false; if(var = true) { System.out.println(“TRUE”); } else { System.out.println(“FALSE”); }

A Vector is declared as follows. What happens if the code tried to add 6 th element to this Vector new vector(5,10)

int x = 2; switch (x) { case 1:System.out.println(“1?); case 2: case 3:System.out.println(“3?); case 4: case 5:System.out.println(“5?); }

Is sizeof a keyword ?
