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

Question

Can anyone help me understand what is the continue keyword in Java? And why it is used?

Answer 1

Basically, the continue keyword will re-execute the condition for while or do loop and also, update the expression for the for loop. It is usually used for early termination of the loop processing and also comes into play to prevent deeply-nested if statements. You can take the below code as a reference:

while (getNext(line)) {

  if (line.isEmpty() || line.isComment())

    continue;

  // More code here

}

I hope this will help.
