For loop

You have a task that requires executing a certain block of code repeatedly, or you need to traverse through elements in a collection like an array or a list. That's where for loops come into play! allowing you to automate repetitive tasks with ease and efficiency.

Understanding For Loops

In Java, a for loop provides a concise way to iterate over a range of values or elements in a collection. It consists of three main parts: initialization, condition, and iteration expression, all enclosed within parentheses and separated by semicolons.

Syntax of For Loop:

for (initialization; condition; iteration) {
        // Code to be executed repeatedly
        }

Example:

Let's say we want to print numbers from 1 to 5:

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

Foreach Loop

The foreach loop, also known as the enhanced for loop, provides a simplified way to iterate over elements in an array or a collection without the need for explicit indexing. It's perfect for situations where you want to iterate through each element sequentially without worrying about index management.

Syntax of Foreach Loop:

for (type variableName : array/collection) {
    // Code to be executed for each element
}

Example:

Let's iterate over elements in an array and print each element:

class ForLoop{
    public static void main(String[] args) {
        int[] numbers = {1, 2, 3, 4, 5};

        for (int number : numbers) {
            System.out.println(number);
        }
    }
}

Java for loops, along with the foreach loop, Whether you're iterating over a range of values or traversing through elements in a collection, for loops provide a concise and efficient way to automate repetitive tasks.

So, the next time you find yourself needing to repeat a block of code or iterate through elements, remember the power of for loops. With a little creativity and practice, you'll be able to tackle a wide range of programming challenges with ease.
