Java program: Read Matrix with Scanner nextInt() – Part 1
Java program: Read Matrix with Scanner nextInt() – Part 1
Welcome to CodeWithBK — your go-to hub for mastering Java programming.
In this video, you will learn how to read an integer matrix in Java using the Scanner class with the nextInt() method. This step-by-step tutorial is perfect for Java beginners who want to understand how to take matrix input from the user in a clean and simple way.
Input given is number of rows and number of columns for the matrix ( 2D Array ), followed by the elements of the matrix.
Example:
Input:
2
3
4 5 6
7 8 9
(The first two lines of input are the number of rows and numbers of columns for the 2D array.
Input is to read a 2D array of size 2x3, i.e. 2 rows and 3 column. )
This is Part 1 of 2.
What you’ll learn in this video:
Brief explanation of how a Scanner class works in Java
Use nextInt method of Scanner class to read integer input
How to declare and initialise a 2D integer array in Java
Using Scanner and nextInt() to read matrix values
reading the number of rows and columns and then reading the values into the matrix
