What is the “continue” keyword and how does it work in Java?

Question

I saw this keyword for the first time and I was wondering if someone could explain to me what it does.

• What is the continue keyword?
• How

Answer 1

If you think of the body of a loop as a subroutine, continue is sort of like return. The same keyword exists in C, and serves the same purpose. Here's a contrived example:

for(int i=0; i < 10; ++i) {
  if (i % 2 == 0) {
    continue;
  }
  System.out.println(i);
}

This will print out only the odd numbers.
