Which capability exists as a method in only one of the two classes when comparing java.io.BufferedWriter and java.io.FileWriter?

class test{

public static void main (String[] args) {

   int x=10,y=15;

   if(~x!=10 || ~y<15)

   {

       x--;

   }

   else

   {

       y++;    

   }

   System.out.println(x+" "+(--y));

}

}

What is the output of the following Java program?

 Statement 3- Hashtable class object uses the key to store value 

Predict the output of the following Java code.

class Abekus implements Runnable {

public

void run()

{

System.out.println("Code Run");

}

} class AbekusMain {

public

static void main(String[] args)

{

Abekus o = new Abekus();

o.start();

System.out.println("Main code run");

}

}

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(ref.getSuperclass());

        }

    }
