In this post, we will learn to create 2×2 matrix using java
We all know that In mathematics Matrix is a two dimensional array with rows and column as like above image. Here we are going to create that matrix using java
Java have a feature to create two dimensional array as like below
Two dimensional array Syntax
int a[][] = { { 1, 2 }, { 2, 4 } };The above array will convert as like below image
Example
public class CreateMatrixExample {
public static void main(String[] args) {
try {
// Creating 2x2 matrix
int a[][] = { { 1, 2 }, { 2, 4 } };
// printing above 2d array in matrix format
for (int i = 0; i < a.length; i++) {
for (int j = 0; j < a[i].length; j++) {
System.out.print(a[i][j] + " ");
}
System.out.println();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}Output
1 2
2 4
