Thread: Sorting/Lexicographic =)

Need help =)..

Question: Write a program that reads in four strings and prints the lexicographically smallest and largest one:
enter four strings:
Charles
Alex
Delta
Baker

Output: The Lexicographic minimum is Alex.
The Lexicographic maximum is Delta.

//project
 
import java.util.Arrays;
import java.io.*;
 
 
 
public class testing {
    public static void main(String[] args)throws IOException {
    	BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
		String name1,name2,name3,name4;
 
		System.out.println("Enter 1st: ");
		name1 = br.readLine();
		System.out.println("Enter 2st: ");
		name2 = br.readLine();
		System.out.println("Enter 3st: ");
		name3 = br.readLine();
		System.out.println("Enter 4st: ");
		name4 = br.readLine();
 
        String[] names = {name1,name2,name3,name4};
        Arrays.sort(names);
        System.out.println(Arrays.toString(names));
 
    }
}

my program only sort the names.. can someone help me or give me a hint on how can i give the output(" The Lexicographic minimum is Alex. The Lexicographic maximum is Delta.")

because i dont have any idea on how can i pick the minimum and maximum.. i dont know what will i do to my first program.. help me T_T

thanks in advance =)

You can reference elements in the array using [] and an index.

String[] someStrings = {"hello" , "world", "today", "is", "a", "sunny", "day"};
System.out.println("The first string in the array is " + someStrings[0]);
System.out.println("Teh last string in the array is " + someStrings[someStrings.length - 1]);
