Adding an Object to Vector loses Reference using Java?
- by thechiman
I have a Vector that holds a number of objects. My code uses a loop to add objects to the Vector depending on certain conditions. My question is, when I add the object to the Vector, is the original object reference added to the vector or does the Vector make a new instance of the object and adds that?
For example, in the following code:
private Vector numbersToCalculate;
StringBuffer temp = new StringBuffer();
while(currentBuffer.length() > i) {
//Some other code
numbersToCalculate.add(temp);
temp.setLength(0); //resets the temp StringBuffer
}
What I'm doing is adding the "temp" StringBuffer to the numbersToCalculate Vector. Should I be creating a new StringBuffer within the loop and adding that or will this code work? Thanks for the help!
