I am sure that you would be familiar with these two patterns.
This brings us to the end of this ‘For Loop in Java’ article. I hope the concept of “for loop in Java” is clear to you now. We will keep digging the Java world together. Stay tuned!

What is a While Loop in Java and how to use it?
Java language offers you to work with several loops. Loops are basically used to execute a set of statements repeatedly until a particular condition is satisfied. Here, I will tell you about the ‘while’ loop in Java. The topics included in this article are mentioned below:

What is a while loop in Java?
The Java while loop is used to iterate a part of the program again and again. If the number of iteration is not fixed, then you can use while loop.
A pictorial representation of how a while loop works:

In the above diagram, when the execution begins and the condition returns false, then the control jumps out to the next statement after the while loop. On the other hand, if the condition returns true then the statement inside the while loop is executed.

What is for-each loop in Java?
The for-each loop in Java is generally used for iteration through the array elements in different programming languages. Java 5 introduced this for-each loop, which is also called as an enhanced for-each loop. So, in this article, I’ll help you guys get a proper gist about how for-each loop in Java works.
Importance of for-each loop
Using a for-each loop, you can traverse a given array. It starts with the keyword for followed by the condition.
This for statement is a very commonly used looping statement. It includes initialization of an expression that specifies an initial value for an index, and the following condition expression determines whether the loop is continued or not and the last iteration expression allows the index to be modified at the end of each pass. It is known as the for-each loop because it traverses each element one by one.
Also, it is recommended to use the for-each loop in Java for traversing the elements in the array and collection because it makes the code readable really good.
Now let’s take a look at the syntax of this for-each loop.

Now let’s take a look at the syntax of this for-each loop.
- Declaration starts with the keyword for like a normal for-loop.
- Instead of initializing a loop counter variable, declare a variable that is of the same type as the base type of the array, followed by a colon, which is then followed by the array name in Java.
- In the body of the loop, you can use the loop variable you created rather than using an indexed array element.
- It’s commonly used to iterate over an array or a Collections class.

What is a Do while loop in Java and how to use it?
The Java do-while loop is used to iterate a set of statements until the given condition is satisfied. If the number of iteration is not fixed and you MUST have to execute the loop at least once, then use a do while loop. In this tutorial, you will learn all about do while loop in Java and how to use it.
Let us dive into the article and explore the following topics:

What is Do while loop in Java?
Do-while loop is similar to while loop, but it possesses one dissimilarity: In while loop, the condition is evaluated before the execution of loop’s body but in do-while loop condition is evaluated after the execution of loop’s body.
I will make the concept visually clear through this flow diagram.

I will make the concept visually clear through this flow diagram.
Let me explain the above-shown diagram:
1 First of all, it will execute a set of statements that are mentioned in your ‘do’ block.
2 After that, it will come to ‘while’ part where it checks the condition.
3 If the condition is true, it goes back and executes the statements.
4 If the condition is false, it directly exits the loop.
Now, moving on towards the syntax of do while loop in Java
