this gives details of the network programming

// Another Sum Java class, this one creates an object of class Sum1
// 
// This sample reads a bunch of integers entered as command line arguments
//   sums them up and prints the sum and average.

public class Sum1 {

	//Create a Sum1 object 
	Sum1 s = new Sum1(args);
    }

    // constructor

	// create an int array of the right size
	int[] ivals = new int[nums.length];

	// convert each string to integer
	for (int i=0;i<nums.length;i++) {
	    ivals[i]= Integer.parseInt(nums[i]);
