Increment for Loop by 2 in Java

In this post, we will see how to increment for loop by 2 in Java.

There are several looping statements available in Java and one of them is for loop in java.

There are three parts of for loop.

• Initialization
• Condition
• Increment or decrement

Initialization: Initialization statement executes at start of loop only one time.
condition:Condition gets evaluated in each iteration. For loop executes block of statements in loop unless condition returns false.
Increment/Decrement: These statements get executed in each iteration.

How to increment for loop by 2 in Java

To Increment for loop by 2 in Java, we are interested in Increment/Decrement part of for loop.

We need to use i+=2 in case we need to increment for loop by 2 in java.

Let’s say we want print all even numbers between 1 to 20 in Java.

We can write a for loop and start the loop from 2 by using i=2 in initialization part and increment the loop by 2 in each iteration by using i+=2.

Here is the program:

Output

How to increment for loop by n in Java

We can use similar logic in case you want to increment for loop by n i.e. 2,3,4,5. We need to put i+=n in increment/decrement part of the for loop.

Here is simple program where we will increment for loop by 3.

Output

That’s all about how to increment for loop by 2 in Java.
