Mar 24, 2025 · In this article we cover different methods to print 2D Array. When we print each element of the 2D array we have to iterate each element so the minimum time complexity is O ( N *M ) where N is the number of rows in the matrix and M is the number of columns in the matrix.

Aug 23, 2024 · In this tutorial, we’ll get familiar with some ways to print 2D arrays, along with their time and space complexity. 2. Common Ways to Print a 2D Array. Java, a versatile programming language, offers multiple methods for handling and manipulating arrays.

Jun 16, 2023 · One of the best ways to print a 2D array in Java is to simply convert the array to a string. A 2D array can also be imagined to be a collection of 1D arrays aligned either row-wise or column-wise. We can use the Arrays.toString () functions for converting these 1D arrays to strings, which will allow us to print their value easily.

Jan 30, 2012 · To then print your 2d array of these objects you can write: for(int j = 0; j < cells[i].length; j++){ System.out.print(cells[i][j]); //invokes toString method in Human.. if(j < cells[i].length -1) System.out.print(", "); System.out.println(); Override the toString () method in your humans class and print what you want to be printed for a human.

Nov 25, 2019 · Given a 2d array arr in Java, the task is to print the contents of this 2d array. The first thing that comes to mind is to write a nested for loop, and print each element by arr [i] [j]. For this, we will use deepToString () method of Arrays class in the util package of Java. This method helps us to get the String representation of the array.

Jun 3, 2024 · In Java, there are several ways to print a 2D array. In this guide, we will see various programs to print 2D array using different approaches: Note: In the previous tutorial, I have covered how to print an array (1D array). 1.

Below are some examples of how to print a 2d array in java: In the below example, we will show an example of how to print an array of integers in java. Code: for (int r = 0; r < matrx.length; r++) { //for loop for row iteration. for (int c = 0; c < matrx[r].length; c++) { //for loop for column iteration.
