The for loop

for statement

Syntax:

for (initialization; condition; update)
  statement

• initialization is an expression with side-effect that initializes a control variable (typically an assignment), which can also be a declaration with initialization
• condition is an expression of type boolean
• update is an expression with side-effect that typically consists in updating (i.e., incrementing or decrementing) the control variable
• statement is a single statement (also called body of the for loop)

Semantics: is equivalent to

{
  initialization;
  while (condition) {
    statement
    update;
  }
}

(There is an exception in the case of the continue statement, which needs to be translated in a more complicated way.)

Example: Print out 100 stars.

for (int i = 0; i < 100; i++)
  System.out.print("*");
