Java – for loop with Syntax, Flowchart and Example.

The Java for loop allows the user to iterate a part of the program multiple times. If a user is certain about how many specific numbers of times the loop must be executed then for loop is recommended. It is also an entry-control loop but here flow control contains three steps:

• initialization = The first step is the initialization of the variable and is executed only once. And need to end with a semicolon(;).
• condition = Second is condition check, it checks for a boolean expression. If true then enter the block and if false exit the loop. And need to end with a semicolon(;).
• Increment or Decrement = The third one is the increment or decrement of the variable for the next iteration. Here, we need to use the semicolon(;).

Flowchart of for loop in Java:

Syntax of for loop:

for(initialization; condition; Increment or Decrement) 
 {
  // Statements
 } 

Example of for loop in Java:

 public class ForTest 
 {
  public static void main(String args[]) 
  {
    for(int a = 1; a < 10; a++) 
    {
    System.out.println("value of a : " + a );
    }
  }
 }

Output:

 value of a : 1
 value of a : 2
 value of a : 3
 value of a : 4
 value of a : 5
 value of a : 6
 value of a : 7
 value of a : 8
 value of a : 9
