I am looking at somebody else's code and I found this piece of code:
for (;;) {
I'm not a Java expert; what is this line of code doing?
At first, I thought it would be creating an infinite loop, but in the very SAME class this programmer uses
while(true)
Which (correct me if I'm wrong) IS an infinite loop. Are these two identical? Why would somebody change their method to repeat the same process?
Any insight would help,
Thanks!

For creating a loop that runs infinitely, we can use empty statements. However, if we use break statements inside the body of the loop, then the loop can terminate. If we want to create a for-loop or while loop that has an empty body, we can use an empty statement.
Yes it is perfectly correct to do so.
Note that methods do not have to take any parameters, but you still need the parentheses after the method name. Procedural abstraction allows a programmer to use a method by knowing in general what it does without knowing what lines of code execute.
Remember the three clauses of the for() are [1] initialization [2] termination and [3] increment. Since the termination clause is empty the loop never terminates. This is directly taken from C syntax.

Those two lines would have the same effect. I can't think of a good reason to use the first one unless you like to confuse people. I guess it's less characters.
