Is it compulsory to use hibernate.cfg.xml for configuration in hibernate?

What should the return type be for a method that has no return value?

What is the output of the following Java code?

public class Abekus {

public static void main(String[] args) {

System.out.println('A' + 'b' + 'e' + 'k' + 'u' + 's');

}

}

What is the output of the following Java code?

class Abekus {

public static void main(String[] args)

{

try

{

System.out.println(10/0);

}

}

}

What is the output of the following Java code?

class Abekus {

public static void main(String[] args)

{

throw new Abekus();

System.out.println("Welcome to Abekus");

}

}

What is the output of the following Java code?

public class Test {

public static void main(String[] args) {

int x = 6;

float y = 9, z;

z = x * y;

System.out.println(x * y);

}

}

Predict the output of the following Java code:

public class Abekus

{

public static void main(String[] args)

{

int i = 7, j = 8 + --i;

int k = --i + ++i / j++ * i++ + ++j % i--;

System.out.println(k);

}

}

class A{

 final int i=20;

  }

 class B extends A{

  final int i=30;

   }

 class C extends B{

  int i=40;

   }

 class testcase extends C{

 int i=50;

  public static void main(String args[]){

     testcase obj = new A();

System.out.println(obj.i);

   }

 }

//Predict the output

import java.util.Scanner;

public class Main

{

    public static void main(String args[])

    {

        StringBuilder str = new StringBuilder("WelcomeWorld");

        int codepoints = str.codePointCount(1, 8);

        System.out.println(codepoints);

    }

}

What will be the code output?

//First Class definition.

package com.pk3;

class Abekus{

 protected void m1()

{

 System.out.println("Protected method of Abekus has been called.");

}

}

//Second class definition.

package com.pkg2;

import com.pk3.Abekus;

public class def extends Abekus {

 public static void main(String args[]) {

  def d=new def();

  d.m1();

}

}

Note: Two classes are there.class def inherit the class Abekus.
