Aug 9, 2013 · Java has different for-loops to walk through a list. For example: public void myMethod(List list) { for (int i = 0; i <= list.size(); i++) { ... } } Or, we can write something like this: public void myMethod(List list) { for (String obj : list) { ... } } Or, we can use a list iterator:

Dec 17, 2021 · In Java, just unlikely any programming language provides four ways for executing the loops namely while loop, for loop, for-each loop, do-while loop or we can call it basically three types of loops in some books as for-each loop is treated as …

Apr 22, 2025 · A Java for loop is a control flow statement that executes a block of code repeatedly based on a given condition and specified iterations. It consists of three parts: initialisation, condition, and update.

Oct 18, 2018 · for loop: for loop provides a concise way of writing the loop structure. Unlike a while loop, a for statement consumes the initialization, condition and increment/decrement in one line thereby providing a shorter, easy to debug structure of looping.

Sep 10, 2024 · In this section, we will discuss the differences between for loop and for-each loop. One well-known method of iterating over an array or a collection of data in Java is the classic for loop. It gives you precise control over the iteration process by letting you directly define the condition, update, and initialization statements.

Apr 20, 2022 · While loop and for loop evaluates the test expression before allowing entry into the loop, hence are entry-controlled loops whereas, do-while is an exit-controlled loop as it evaluates the test expression after executing the body of the loop once.

Java has two main ways of looping, and those are the for loop and the while loop. We'll explore both types and see how they work.

When you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop: Statement 1 is executed (one time) before the execution of the code block. Statement 2 defines the condition for executing the code block. Statement 3 is executed (every time) after the code block has been executed.

What is the difference between a for loop and a while loop? A for loop is used when the number of iterations is known, while a while loop is used when the loop runs based on a condition. 4.

Oct 27, 2023 · For-loops can be thought of as shorthands for while-loops which increment and test a loop variable. The “for” loop provides a convenient and concise way to specify the initialization, condition, and update steps for the loop. Here’s the basic syntax of a “for” loop in Java: Let’s break down each part of the “for” loop:
