Question

I am working with vectors and when I copy the data and try to edit it the vector and the copy both change.

//The vectors contains int[] and the first 3 are loaded with int values.
int ToCheck[] = OpenSet.elementAt(Current);
ToCheck[1] = ToCheck[1] + 1; // This changes OpenSet and ToCheck[].
boolean IsInVector = false;

for(int y = 0;y < OpenSet.size(); y++){
     if(ToCheck == OpenSet.elementAt(y)) // Because it changed both values it always is true
     {
    IsInVector == true;
     }
}

I want to be able to copy the data in the vector and edit it without changing the original.

Answer 1

The simple way to copy an array is to use Arrays.copyOf:

int[] tmp = openSet.elementAt(current);
int toCheck[] = Arrays.copyOf(tmp, tmp.length);

And while you are listening, PLEASE learn to use the accepted Java naming conventions. Method names and field/parameter/local names should start with a lower-case letter.
