What is HotJava?

Select the correct option that gives compile-time errors in this code.

Which of these methods of the Java String class is used to remove leading and trailing whitespaces?

class test{

public static void main (String[] args) {

  int x=1,y=16;

  x=x>>2;

  y=y>>x;

  System.out.println(x);

}

}

class GFG {

public static void main (String[] args) {

        byte x = (byte)64;

             int i;

             byte y; 

             i = x>>3;

             y = (byte) (x<<2);

             System.out.print(~i + " " +y);

}

}

Predict the output of the following Java code.

class Abekus {

protected int a, b;

}

class Abekusmain {

public static void main(String args[]) {

Abekus o = new Abekus();

System.out.println(o.a + " " + o.b);

}

What is the output of the following Java code?

class Abekus {
static int i = 10;
public static void main(String[] args) {
Abekus o1 = new Abekus();
Abekus o2 = new Abekus();
o1.i = 20;
System.out.print(o1.i + " ");
System.out.println(o2.i);
}
}

Predict the output of the following Java code:

import java.util.*;

public class Abekus {

public static void main(String[] args) {

LinkedList l = new LinkedList();

l.add(6);

l.add(8);

l.add(4);

l.add(2);

System.out.println(l.pollFirst());

System.out.println(l.pollLast());

}

}

Predict the output of the following Java code.

class Abekus {

    void abbu() {

        String s = "Hey, ";

        String s1 = dabbu(s);

        String s2 = " How are";

        System.out.print(":"+s2 + s1); }

    String dabbu(String s) {

        s = s + "Abekus Learner! ";

        System.out.print(s);

        return " you?"; }

    public static void main(String[] args) {

        Abekus o = new Abekus();

        o.abbu();  }

}

import java.util.*;

    class output 

    {

        public static void main(String args[]) 

        {

            LinkedList set = new LinkedList();

            set.add("A");

            set.add("B");

            set.add("C");

            set.add("D");

   set.addFirst("F");

            set.addLast("G");

            Iterator i = set.iterator();

            Collections.reverse(set);

       Collections.shuffle(set);

  System.out.println(set.pollFirst()+" "+set.peekLast());

  System.out.println(set.peekFirst()+" "+set.pollLast());

                   }
