Question 795 – OOPS

class simple  {       public static void main(String[] args)       {            simple obj = new simple();            obj.start();      }       void start()      {           long [] P = {3, 4, 5};            long [] Q = method (P);            System.out.print (P[0] + P[1] + P[2]+”:”);            System.out.print (Q[0] + Q[1] + Q[2]);       }      long [] method (long [] R)       {            R [1] = 7; return R;       } } //end of class 

• First we will create the object of simple class.
• By using object , we call the function start( ).
• In the start() function definition, first statement is integer array with three elements.
• long [ ] Q= method (P); Again function method(p) will be called.
• In the definition of method function, we are changing the second element of array to value 7 and returning updated array to array Q.
• We are passing address of P as argument to method so Modifications happened in the method automatically reflects to array P.
• Both array P and Q consists of values {3,7,5}.
• The sum of the three values are 15.
