Sort Names in Array Program - Java Programs

Write a program to store 10 names in an array. Arrange these in alphabetical order by sorting. Print the sorted list. Take single word names, all in capital letters, e.g. SAMSON, AJAY, LUCY, etc.

Java 

import java.io.*;
class Menu{
    public static void main(String args[])throws IOException{
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String a[] = new String[10];
        System.out.println("Enter " + a.length + " names:");
        for(int i = 0; i < a.length; i++){ a[i] = br.readLine().toUpperCase(); a[i] = a[i].trim(); if(a[i].indexOf(' ') > 0)
                a[i] = a[i].substring(0, a[i].indexOf(' '));
        }
        for(int i = 0; i < a.length; i++){
            for(int j = 0; j < a.length - 1 - i; j++){ if(a[j].compareTo(a[j + 1]) > 0){
                    String temp = a[j];
                    a[j] = a[j + 1];
                    a[j + 1] = temp;
                }
            }
        }
        System.out.println("Sorted List of names:");
        for(int i = 0; i < a.length; i++)
            System.out.print(a[i] + "\t");
    }
}
