I don't understand how to locate and remove an object from an array of integers?

I have no f'n clue.

Example array of integers: Integer[] a = { new Integer(32), new Integer(21) } To access the elements: a[0] a[1] You cannot remove them directly. If you do not want to shrink the array size, just make it zero, such as, a[1] = new Integer(0); If you want to shrink the array size and remove a[1] from the array for example, there's no direct way. You need to write a method to do it.

Jeez, it's not like she asked us to do her homework, like most everyone else. Anyway, to take out an element from an array, you have to copy the next element into the element you want to get rid of, then copy the next element into the space of the element you just moved, and so on. Arrays can't be resized, so this doesn't change the amount of memory used. Check out the collections interfaces for more functional ways of storing data. And yes, you should probably be picky about what you call an object, because it does make a difference in Java. int []intArray = {1,2,3,4,5,6}; int indexToRemove = 3; // or whatever for (int i = indexToRemove;i < intArray.length-1;i++) { intArray[i] = intArray [i+1]; } intArray[intArray.length-1] = 0;
