for loop in java


Execute a sequence of statements multiple times and abbreviates the code that manages the loop variable.


Syntax

The syntax of a for loop is −

for(initialization; Boolean_expression; update) {
   // Statements
}

Here is the flow of control in a for loop −

  • The initialization step is executed first, and only once. This step allows you to declare and initialize any loop control variables and this step ends with a semi colon (;).

  • Next, the Boolean expression is evaluated. If it is true, the body of the loop is executed. If it is false, the body of the loop will not be executed and control jumps to the next statement past the for loop.

  • After the body of the for loop gets executed, the control jumps back up to the update statement. This statement allows you to update any loop control variables. This statement can be left blank with a semicolon at the end.
