I'd like to set all the values in a boolean array to false without re-initializing it

Question

    public boolean used[] = new boolean[26];

Here is what I have, and it's working great. I know they are all going to be set as false by default. But, as my application is used for a while, some of those are changed to "true". (Which is fine, since that's what my code is supposed to do).

I'm trying to create a "reset" button, which will simulate a reset-like action. Where all variables are restored to what they were when the window was initially created (all drawings go away - just a fresh restart).

And I need all of those true booleans to go back to false in one fell swoop. Any ideas?

Solution 1

Use Arrays.fill:

Arrays.fill(used, false);

Solution 2

You can just recreate your array, it will be initialized by default to false.

That is when you implement the reset yo can do

used[] = new boolean[26];

Solution 3

Use java.util.Arrays.fill():

Arrays.fill(used, false);
