Java Tutorial: Multidimensional Arrays in Java code example
Example 1: java two dimensional arrays
int[][] multiples = new int[4][2]; // 2D integer array with 4 rows
and 2 columns
String[][] cities = new String[3][3]; // 2D String array with 3 rows
and 3 columns
Example 2: 2d array java
//Length
int[][]arr= new int [filas][columnas];
arr.length=filas;
int[][] a = {
{1, 2, 3},
{4, 5, 6, 9},
{7},
};
// calculate the length of each row
System.out.println("Length of row 1: " + a[0].length);
System.out.println("Length of row 2: " + a[1].length);
System.out.println("Length of row 3: " + a[2].length);
}
