replace the element of an array of objects

P: 20
Can anyone help me??

I have an array of objects for a class. The class has two arraylist variables.

I want to

1) replace one particular object with another object with new arraylist values.

2) replace another particular object with arraylist values set to null

3)in the output, objects in the array should be in an order in which the object having arraylist values set to null (the object in 2 point) should be in the end of the array of objects..

To replace an object in an array just assign the index to the new object

Expand|Select|Wrap|Line Numbers
  1. objectArray[index] = theNewObject;
To replace an object in an arraylist just use the ArrayList.set method

Expand|Select|Wrap|Line Numbers
  1. arrayList.set(index, theNewObject);
