Question by Alex: Using semaphores in Java? How can I make threads run at different frequencies to one another?
I have three different threads running in my Java program. One prints “1″, another “2″, and the last “3″. I need to make the “1″s and “2″s print less frequently than the “3″, using semaphores, but I’m very stuck. Any ideas?

Best answer:

Answer by McFate
You could wait on one semaphone between all three threads, and then:

(1) Print “3″ every time you get the semaphore in the “3″ thread
(2) Print “1″ only every second or third time you get the semaphore in the “1″ thread

• I

In the early 1990s, a team of developers at Sun Microsystems, led by James Gosling, designed and implemented a new computer language: Java. The language was object oriented, was compiled into an intermediate form called Java Bytecode, and those bytecode instructions were run on a virtual machine called the Java VM. Java, at the time, was a revolution in itself. It quickly became the language of a new generation of software developers who were writing small applications for the web, server applic

Thank you so much.
Also can you have more than one compareTo in a program? I need it for two methods but the first methods results will override the second even if I do not initiate the first method.

Answer by michaeljhuman
Try str.compareTo().

I don’t think == works, as that compares the object reference, not the string contents.
