- The for loop - has a repetition control structure that allows you to effectively write a loop that must be executed a certain number of times.
- The for loop is useful when you know how many times a task needs to be repeated.
The for loop syntax in Java:
The control process in the cycle:
- The initialization phase is performed first, and only once. This step allows you to declare and initialize any variables to control the loop, and it ends with a semicolon (;).
- Next is a logical expression. If true, the loop body is executed if it is false, the loop body is not executed, and control passes to the next statement past the loop.
- After the for loop is executed, the control goes back to the update operator . It allows you to update any variables for loop control, and is written without a semicolon at the end.
- The logical expression is now evaluated again. If it is true, the loop is executed and the process is repeated. If it is false, then the for loop terminates.
