Question

How do you order multiple strings in java alphabetically using ASCII/Unicode orders and string operations?

Where the input of the strings is done using args[0], args[1], args[2] , etc...

import java.util.Arrays;
public class TestCode {
    public static void sort(String s[]){
        int n = s.length, j;
        for (int i=1; i<n; ++i){
            String key = s[i];
            j = i-1;
            while (j>=0 && s[j].compareTo(key)>0){
                s[j+1] = s[j];
                j = j-1;
            }
            s[j+1] = key;
        }
    }

    public static void main(String args[]){
        if(args.length==0){
            System.out.println("Please pass some command line arguments");
        }
        else{
            String s[] = new String[args.length];
            for(int i = 0;i<args.length;i++){
                s[i] = args[i];
            }
            sort(s);
            System.out.println("Order of strings in alphabetical order:");
            for(int i = 0;i<s.length;i++){
                System.out.print(s[i]+" ");
            }
            System.out.println();
        }
    }
}
