      Hello again. I forgot to add that data items are read into the two arrays, x and y.
      Then, i have to store the product of corresponding elements of x and y in a third
      array,z. How do i go about multiplying arrays? Can anyone give me the codes? After
      that, i have to compute and display the square root of the sum of the items in z.

      Please help me here.

      Thanks a lot!

      you don't say how many dimensions, the size of the
      array, or what type of data the arrays hold...

      here is a solution for one-dimensional arrays of
      a fixed number of type int data:

      // create a class that has these variables
      static int ARRAYELEMENTS = 4;

      int [] x, y, z;

      x = new int [ARRAYELEMENTS];
      y = new int [ARRAYELEMENTS];
      z = new int [ARRAYELEMENTS];

      x = {1, 2, 3, 4};
      y = {4, 3, 2, 1};

      z = multiplyArrays (x, y);


      // this would be a method in the class you create
      public int [] multiplyArrays(int [] a, int [] b)
      {
      for (int i = 0; i < ARRAYELEMENTS; i++)
      {
      a[i] *= b[i];
      }
      return a;
      }


      good luck...
