java 2d array init code example
Example 1: two dimensional array in java example program
String[][][] data = new String[3][4][2];
Example 2: Java 2d array initialization
class TwoDimensionalArray {
public static void main(String[] args) {
String[][] salutation = {
{"Mr. ", "Mrs. ", "Ms. "},
{"Kumar"}
};
// Mr. Kumar
System.out.println(salutation[0][0] + salutation[1][0]);
// Mrs. Kumar
System.out.println(salutation[0][1] + salutation[1][0]);
}
}
The output from this program is:
Mr. Kumar
Mrs. Kumar
Example 3: two dimensional array in java example program
class MultidimensionalArray {
public static void main(String[] args) {
// create a 2d array
int[][] a = {
{1, -2, 3},
{-4, -5, 6, 9},
{7},
};
// first for...each loop access the individual array
// inside the 2d array
for (int[] innerArray: a) {
// second for...each loop access each element inside the row
for(int data: innerArray) {
System.out.println(data);
}
}
}
}
Example 4: how to initialize one dimensional array in java
int[] a; // valid declaration
int b[]; // valid declaration
int[] c; // valid declaration
