Which of these methods can set the output stream to OutputStream?

The built-in base class in Java, which is used to handle all exceptions, is:

  variables of interface should be 

The class support one default constructor stack() which is used to

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));

}

}

public class outputs 

    {

        public static void main(String args[]) 

        {

            int a=10;

int b=20;

int c=30;

int sum=0;

sum= ++a + ++b + ++b*c + ++a*c ;

System.out.println(sum);

        } 

    }

What will be the output of the following Java code?

class Output

{

public static void main(String[] args)

{

String c = "Hello i love java";

int start = 2;

int end = 9;

char[] s = new char[end - start];

c.getChars(start, end, s, 0);

System.out.println(new String(s));

}

}

 class first 

    {

        int a;

        void show() 

        {

            System.out.println(a);

        }

    }    

    class  second extends first 

    {

        int b;

        void show() 

        {

            System.out.println(b);

        }

    }    

      class output 

    {

        public static void main(String args[])

        {

            second obj = new second();

            obj.a=1;

            obj.b=2;   

            obj.show();     

        }

   }

import java.util.*;

    public class outputs 

    {

        public static void main(String args[]) 

        {

            LinkedList list = new LinkedList();

            list.add(new Integer(3));

            list.add(new Integer(9));

            list.add(new Integer(5));

            list.add(new Integer(1));

   list.addFirst(new Integer(6));

   list.addLast(new Integer(9));

            Iterator i = list.iterator();

       Collections.sort(list);

            while(i.hasNext())

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

        }

    }

void run(){

System.out.println("father start running");

}

void walk(){

System.out.println("father start walking");

}

class Child extends Father{

}

void walk(){

System.out.println("child start walking");

void sleep(){

System.out.println("child start sleep");
