Write a JAVA program to accept the number from the user and do the following - Calculate Factorial of a given Number. - To check whether given number is prime or not. (Use Thread)

class NewThread implements Runnable
{
     int n=5,f=1;
    Thread t;
    NewThread()
    {
       t=new Thread(this,"factorial");
     System.out.println("Main thread "+t);
       t.start();
    }
        public void run()
       {
          try
           {
              while(n>0)
             {
               f=f*n;
              n=n-1;
             }
               System.out.println(f);                    
                   Thread.sleep(100);
              
       
             }
              catch(InterruptedException e)
               {
                  System.out.println("Exception"); 
               }
                System.out.println("Exiting Main thread");
       }
   
}

class Thread5
{
    public static void main(String args[])
    {
       new NewThread();
    new NewThread1();
                System.out.println("Exiting main thread");
       }
}



class NewThread1 implements Runnable
{
Thread t1;
NewThread1()
{
    t1=new Thread(this,"Prime number");
     System.out.println("t1 is created"+t1);
    t1.start();
}
public void run()
{
int i=2,no=11 ,flag=1;
      
         try
           {
int n2= no/2;
    if(n2==0)
     System.out.println("no.is not prime");
    else
     System.out.println("no.is prime");
                   Thread.sleep(1000);
          }
            catch(InterruptedException e)
               {
                  System.out.println("Exception"); 
               }
}
}
