Java For Loop

The for loop in Java is a control statement used for repetitive execution of a block of code. It’s often used when you know in advance how many times you want to execute a particular block of code. Here’s the basic syntax of a for loop in Java:

for (initialization; condition; update) {
    // Code to repeat
}

• The initialization statement is executed once before the loop begins. It’s typically used to initialize loop control variables.
• The condition is evaluated before each iteration of the loop. If the condition is true, the loop continues; if it’s false, the loop terminates.
• The update statement is executed after each iteration of the loop. It’s usually used to update loop control variables.

Here’s a simple example that uses a for loop to print numbers from 1 to 5:

public class Main {
    public static void main(String[] args) {
        for (int i = 1; i <= 5; i++) {
            System.out.println(i);
        }
    }
}

In this example:

• int i = 1 is the initialization step, where we declare and initialize the loop control variable i to 1.
• i <= 5 is the condition, which specifies that the loop will continue as long as i is less than or equal to 5.
• i++ is the update statement, which increments i by 1 after each iteration.

The loop will execute five times, printing the numbers 1 to 5.

You can use the for loop for various purposes, such as iterating through arrays, processing data in a list, and performing repetitive tasks with a known number of iterations. The for loop is a powerful tool for managing repetitive tasks in your Java programs.
