Saw an error of the form:
if(something = somethingelse)
which won't compile.

"wek",
The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp . We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please log in with a new name which meets the requirements.
Thanks.

If you wish to compare two things, you should use == instead of = (which is an assignment operator).

[Matts Smith]

Technicalities again... I had to say it
boolean b = false;
if (b = true)
{
System.out.println("I will be printed");
}
later

[Frank Carver]

So yes, that will compile, and it will be printed, but it's not comparing two things. It's assigning true to b, and then self-checking the expression 'b'. What was your point exactly?

if(something = somethingelse)
which won't compile.

I was just pointing out it is possibly a boolean assignment.
