Java two-dimensional array example
A Java 2d array example.
ArrayExample.java
package com.mkyong;
public class ArrayExample {
public static void main(String[] args) {
int[][] num2d = new int[2][3];
num2d[0][0] = 1;
num2d[0][1] = 2;
num2d[0][2] = 3;
num2d[1][0] = 10;
num2d[1][1] = 20;
num2d[1][2] = 30;
//or init 2d array like this :
int[][] num2dInit = {
{1, 2, 3},
{10, 20, 30}
};
print2dArray(num2d);
}
static void print2dArray(int[][] num2d) {
// Accessing 2d array with index print
int index1d, index2d = 0;
for (int[] num1d : num2d) {
index1d = 0;
for (int num : num1d) {
System.out.println("[" + index2d + "][" + index1d + "] = " + num);
index1d++;
}
index2d++;
}
}
}
Output
[0][0] = 1
[0][1] = 2
[0][2] = 3
[1][0] = 10
[1][1] = 20
[1][2] = 30
