Valid Java, compile
Hey I have this question in my assignment and I can't see why it would compile, so confused...any help with this question?
The following code excerpt is valid Java
if (b = check ()){
System.out.println("All is OK.");
}
What can you infer about 'check()' and 'b'?
The syntax for an if-expression is if(boolean expression).
However
b = check() appears to be an assignment expression. Explain why
if (b = check()) does in fact compile.
Would appreciate any help with this guys it has got me stumped.

Hint: What does the assignment operator return? Might have to do some googling or putting together some test programs to figure it out.

Re: Valid Java, compile
How do I put a test program together for that? I am literally starting level and so un confident with Java
Re: Valid Java, compile
How about using a print statement? Something like this:
System.out.println(b = check());
Now, what if the variable is an int? A String? Something else? What happens then?
