What is the output of the following Java program?

Which of the following events is generated by a scroll bar?

class test{

public static void main (String[] args) {

  int x=130;

  byte b=(byte)x;

  System.out.println(b);

}

}

class test {

public static void main (String[] args) {

  int[][] arr=new int[][]{{0,1,2,3,4,5,6,7,8,9},{10,11,12,13,14,15,16}};

      int n=2;

      System.out.println((arr[--n][n*5])/10*2+3/10);

}

}

Predict the output.

class Abekus { 

public static void main(String[] args) 

{ 

int A[] = { 4, 7, 15, 20, 13 };

for (final int i : A) 

System.out.print(i + " "); 

} 

} 

What is the output of the following Java code?

class Abekus {

    public static void main(String args[]) {

      for (int k=0; k<40; k=k+3) {

        if (k % 2 == 1)

          System.out.print(k + " ");

      }

    }

}

Predict the output of the following Java code:

import java.lang.*; class Counter { int count; public void increment(){ count++; }}

public class Main{ public static void main(String args[]) throws Exception{ Counter c=new Counter(); Thread t1 =new Thread (new Runnable() { public void run(){ for(int i=1;i<=1000;i++) { c.increment(); }}});

Thread t2 =new Thread (new Runnable() { public void run() { for(int i=1;i<=1000;i++) { c.increment(); }}});

t1.start(); t2.start(); t1.join(); t2.join(); System.out.println(c.count); }}
