Java Creating a Prime Sieve with Boolean Expressions

[JasonRox]

I'm trying to create a sieve (prime sieve). A nice quick simple one using boolean expressions.

I remember on Visual Basics it began by creating like X number of boolean variables and then sieve them out by classifying them as false... and so on.

How to a create a large group of boolean variables?

I think it was something like p(i) and i=X, which X determined how many to create. It was something like this I think.

So, technically i is like a variable itselt because when I go through the loop, I should be able to go through steps like...

p(4) = false;
p(6) = false;
p(8) = false;

... all the way until I reach 2X.

So, how do you create this variable?

Thanks, I appreciate it.

Create as big of an array as you like.

int X = 1000 ;

boolean [] p = new boolean[X];

Thanks a lot.

I'll see how it turns out.
