Sort within an array?

Question

public class Input3
     private String[] input = new String[40];
     private static int StringNum = -1;
     public static final int NUMBER_OF_TEAMS = 3;
     public static final int NUMBER_OF_PLAYERS = 5;
     public Input3()
          //The first six inputs will be for the first team
          input[0] = "LAKERS";
          input[1] = "Kobe Bryant";
          input[2] = "Derek Fisher";
          input[3] = "Shaquille O'Neal";     
          input[4] = "Karl Malone";
          input[5] = "Brian Cook";
          //The next six inputs will be for the second team
          input[6] = "MAVERICKS";
          input[7] = "Antoine Walker";
          input[8] = "Dirk Nowitzki";
          input[9] = "Tony Delk";
          input[10] = "Shawn Bradley";
          input[11] = "Travis Best";
          //The next six inputs will be for the third team
          input[12] = "KNICKS";
          input[13] = "Mike Sweetney";
          input[14] = "Allan Houston";
          input[15] = "Howard Eisley";
          input[16] = "Kurt Thomas";
          input[17] = "Shanon Anderson";
     //This method returns the strings one after the other.
     public String getNextString()
          StringNum++;
          return input[StringNum];
}What I'm supposed to do with this is sort that data by last names within each team. By that I mean I have to sort input[1] through input[5] by last names, input[7] through input[11] by last names, and same for the Knicks team. I'm not sure how to do 3 separate sorts within an array.
The output should look like this:
KNICKS:
Sharon Anderson
Howard Eisley
Allan Houston
Mike Sweetney
Kurt Thomas
Any help is greatly appreciated!

Yeah, I don't really understand it. But my professor actually gave us that code to work with to be part of a bigger assignment. I actually just posted another question about the same assignment if you want to look at that to see if it might help.
I dunno how to use the insert link button on here so I'll just let you copy and paste if you are interested in helping me out... Thanks!
