Actually, you could probably use

public static void main (String[] main) {

Initialize your class
Write a loop to get your numbers
send to method in that classs

}

So, your answer is. You don't have to use two classes. In fact, just one for your selection sort and have the user input numbers in the public static void part.

hi..
I am writing the code for selection sort, you'll need to pass the numbers for sorting as command line arguments that is along with the command you use to run the java program

e.g., java Selection 12,45,1,76,50

the code is as follows:

class Selection
{
public static void main(String arg[])
{
int x[]; //declaring an empty array,initialized later
int i;

//checking if arguments have been given or not at the command line
if(arg.length==0)
System.out.println("No Arguments Specified...\n");//prints msg if no args specified

else
{
x=new int[arg.lenght]; //initializing the array with the no. of args specified.

try //trapping any errors that might occur
{
for(i=0;i
