Java For Loop

A for loop is used to run a block of code repeatedly for a specified number of times, based on a condition. It is one of the most common control structures in JavaScript.

Syntax:

for (initialization; condition; increment/decrement) { 
  // Code to execute 
}

Initialization: Sets the starting value for the loop variable.
Condition: Specifies when the loop should stop (must evaluate to false to terminate the loop).
Increment/Decrement: Updates the loop variable after each iteration.

Basic For Loop

for (int i = 0; i < 5; i++) {

System.out.println("Iteration number:"+ i);

}

Nested For Loop

for (int i = 1; i <= 3; i++) {

for (int j = 1; j <= 2; j++) {

System.out.print(" "+i*j);

}

System.out.println();

}

Enhanced For Loop (For-Each Loop):

The for-each loop is used to iterate over arrays or collections without using an index. It's simpler and avoids potential errors with index handling.

Syntax:

for (dataType variable : arrayOrCollection) {
    // Code to execute
}

Example

int[] numbers = {10, 20, 30, 40};

for (int num : numbers) {

System.out.println(num);

}
