Multiple inheritance means ? 

what should be the output of this code block?

  public class abekus {

    public static void main(String[] args) {

      String input = "the abekus";

      input = input.replace("the", " ");

      input = input.trim();

      System.out.print(input.length());

    }

  }

Predict the output of the following Java code:

class Abekus {

int i = 10;

public static void main(String[] args)

{

Abekus a = new Abekus();

System.out.println(a.i);

}

static

{

int i = 20;

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

}

}

class Base {

public void show() {

System.out.println("Base::show() called");

}

}

class Derived extends Base {

public void show() {

System.out.println("Derived::show() called");

}

}

public class Main {

public static void main(String[] args) {

Base b = new Derived();;

b.show();

}

}

class human 

    {

        int i;

        double j;

    }

    class child extends human 

    {

int k;

    }

    class output 

    {

        public static void main(String args[]) 

        {

            human i = new human();

            child j = new child();

            Class ref;

            ref = j.getClass();

            System.out.print(j.equals(i));

        }

    }
