How to use For Loop in Java

For Loop in Java is easy as 1 2 3. When you want your code to be executed dynamically instead of doing it manually, use for loop.

Syntax

for (statement 1; statement 2; statement 3) {
//code block
}

Statement 1: Sets a variable with a value. The loop start from here.

Statement 2: This is where you set your condition. Define the condition to run the loop. If the condition is true, It will keep running until it is false.

Statement 3: Increases a value every time until it reaches the end value of the condition or loop.

Example

When you are printing numbers from 1 – 5. Do not code like this. See this example code below.

System.out.println("1");
System.out.println("2");
System.out.println("3");
System.out.println("4");
System.out.println("5");

Output

1
2
3
4
5

Although, the output is the same as expected. But it seems like not a professional one. Your code should be like this.

for (int i = 1; i <= 5; i++) {
    System.out.println(i);
}

Output

1
2
3
4
5
