Array Running Error NullPointerException

Question

I m trying to create a class that will have an overload constructor which will passing a parameter of an Object array.....
public class Standings
          private Team [] footBall;
          /* public Standings()
               footBall = footBall;     
          public Standings( Team [] footBallArray )
                    for(int i = 0; i < footBallArray.length; i++)
                              footBall[i] = footBallArray;                    
Then test it wit a prog which will create an object array then use the overload constructor...Team [] array = new Team[5];
     array[0] = new Team("Alabama", 6, 6);
     array[1] = new Team("Georgia", 7, 4);
     array[2] = new Team("Tennessee", 8, 3);
     array[3] = new Team("Vanderbilt", 4, 8);
     array[4] = new Team("Mississippi", 1, 6);
     // now instantiate the team calling the overloaded constructor
     Standings temp = new Standings(array);
but it alway give me a NullPointerException... cuold some1 show me why... Thankx                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

Answer 1

Obviously the footBall[] is not instantiated
public Standings( Team [] footBallArray )
          for(int i = 0; i < footBallArray.length; i++)
               //------>footBall[i] = footBallArray;                    
modify your code add this statement be for the for looppublic Standings( Team [] footBallArray )
this.footBall = footBallArray;
for(int i = 0; i < footBallArray.length; i++)
OR you could try add these code before and inside the for loop public Standings( Team [] footBallArray )
this.footBall = new Team[footBallArray.length] //before for loop
for(int i = 0; i < footBallArray.length; i++) {
this.footBall[i] = new Team(); // inside the for loop but before your statement
