Thread: Append a string to Vector element

Hi again, I don't find any method that append my string to the vector element.

	Vector<String> v = new Vector<String>();
 
	...
 
	for(int i=0; i<v.size() ;i++)
		v.elementAt(i).concat(" hello");

This just return the v.elementAt(i) with " hello" at the end. but doesn't modify the element. So i should asignate the returned string to other variable .

I can't do this asignation: v.elementAt(i) = v.elementAt(i).concat(" hello");

Imagine all v.elements has 1234 already. Now I want to concat this (I want this output):
v.elementAt(0) = "1234 hello"
v.elementAt(1) = "1234 hello"
v.elementAt(2) = "1234 hello"

but I only get
v.elementAt(0) = "1234"
or
v.elementAt(0) = " hello"
If I use this i get replaced 1234 for hello, instead append it

	for(int i=0; i<v.size() ;i++)
		v.add(i, "hello");

Hehe I'm lucky I know a bit about setter and getter , otherwise I could not understand you .
Didn't expect that I could do this.

Thank you-

SOLVED:

for(int i=0; i<v.size() ;i++){
		 	v.set(i, v.get(i)+" hello");
			System.out.println(v.elementAt(i));
		}
