My systems crushes down if I am testing my method

That won't compile. Try posting code that compiles and provide details about what problems occur when you run it.

When you post code, please use[code] and [/code] tags as described in [url=http://forum.java.sun.com/help.jspa?sec=formatting]Formatting tips[/url] on the message entry page. It makes it much easier to read.

(I think I know what your problem is, but I want you to post the real code and ask a better question.)

1. the second expression must be a boolean expression, not an integer expression (I assume what you meant to say was x == 17000010f).

2. The second term is a continuation condition, not a termination condition. If you execute it as written, in the very first pass, it will test the condition, fail, and exit without having ever moved through the loop even once.

I assume that what you really wanted is x < 17000010f. This will cause the loop to exit when x is equal to (or larger than) 17000010.

Are you assuming that adding 1 to 17000000f will give you 17000001f? Well, that isn't necessarily so. In fact (I just checked with a little test program on my computer) it's actually 17000000f. Floating point representation isn't exact and floats can only represent about 6 significant figures. You have 8 figures there so adding 1 is less than the round-off error.

Edit: ... like those other people said while I was starting up RAD to write my little test program...
