The for keyword in Java programming language

We will learn about the for keyword in Java programming language

In Java programming language, the for keyword is used in the for loop. The for keyword specifies a loop that executes a block of statements repeatedly until given condition (boolean expression) is true. The for loop test expression similar to if condition(based on boolean expression)

In Java language, There are two type of for loop

classic for loop
Enhanced for loop

Syntax

The syntax of the for (classic for loop)

for(initialization; boolean Expression; increment or decrement){
statement(s) //block of statements
}

Example

int i;

for(i=0; i>=max; i++){ //boolean expression
System.out.println(i); // display statements
}

for keyword is used for loop, it executes a block of statements until the boolean expression returns true. It gets terminated when the boolean expression returns false.

Program

The real example to for keyword in for loop in java

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

        }

    }

When the above code is compiled and executed, it will produce the following results

The value of i is :1
The value of i is :2
The value of i is :3
The value of i is :4
The value of i is :5
The value of i is :6
The value of i is :7
The value of i is :8
The value of i is :9
