Java: how do I point at an array item through a variable?

Question

How do I point at an array item through a variable? Example:

String[] names;

int test = 10;

String myName = names[test];

The purpose is to get the same number item from 2 different arrays, for a username/password program.

Answer 1

In your example:

String[] names;
int test = 10;
String myName = names[test];

The variable myName is a reference to the String in the array, but giving it new value:

myName = "fred";

will do nothing to the array - all you'd be doing is assigning a new reference to that variable.

To give the array element a bew value, do this:

names[test] = "fred";
