Java for loop through string9/1/2023 Though it's not necessary to use for loop, you can even use while loop or advanced for loop in Java, it makes sense to start with this simplest of programming construct. Here is a Java program to iterate over a two-dimensional array in Java using traditional for loop. Java Program to Loop over 2D Array in Java array, string, a vector will make sense to you. Once you went through the book, most of the programming concepts e.g. If you are an absolute beginner and just started with programming, I recommend reading Head First Programming first. ![]() That's why we need two loops, nested in each other.Īnytime, if you want to come out of the nested loop, you can use the break statement. In order to loop over a 2D array, we first go through each row, and then again we go through each column in every row. You can think about a two-dimensional array as a matrix that has rows and columns, this helps to visualize the contents of an array. In order to make use of the 2D array, you must know how to populate and iterate over it and that's what you will learn in this article. Whatever you see on your screen is nothing but a 2D array that is populated using tiles. You can use a two-dimensional array to make finite state machine (FSM) solve state-based problems, you can use a 2D array to create board games like Chess, Sudoku, and Tic-Tac-To and you can even use a two-dimensional array to create 2D arcade games e.g. It's one of the most useful data structures in the programming world. Though it's not common to see an array of more than 3 dimensions and 2D arrays is what you will see in most of the places. Similarly to loop an n-dimensional array you need n loops nested into each other. ![]() You can loop over a two-dimensional array in Java by using two for loops, also known as nested loop.
