Which AWT component can contain other components like buttons, text fields, and labels?

How can we restrict certain variables of a class from getting serialized?

How many times 'abekus' is printed?

public class abekus

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.poll());

System.out.println(l);

}

}

Predict the output of the following Java code:

public class Abekus {
public static void main(String[] args)
{
Integer a = 128, b = 128;
Integer c = -130, d = -130;
Integer e = 122, f = 122;
Integer g = -127, h = -127;
System.out.println((a==b) + " " + (c==d) + " ");
System.out.println((e==f) + " " + (g==h));
}
}

Select the correct option for this Java code.

class Abekus {

public static void main(String[] args)

{

int a = 15;

final int b = 34;

int c = 45;

switch (a) {

case 15:

System.out.println("Hi, "); //line 1

break;

case b:

System.out.println("Abekus "); //line 2

break;

case c:

System.out.println("Learner"); //line 3

break;

}

}

}
