how to get the dimensions of a 2d array in java
public class Main {
public static void main(String[] args) {
int[][] test = new int[10][4];
int rows = test.length;
int coloumns = test[0].length;
System.out.println(rows);
System.out.println(coloumns);
}
}java length of matrix
public static void main(String[] args) {
int[][] foo = new int[][] {
new int[] { 1, 2, 3 },
new int[] { 1, 2, 3, 4},
};
System.out.println(foo.length); //2
System.out.println(foo[0].length); //3
System.out.println(foo[1].length); //4
}java 2d array length
int[][] test;
test = new int[5][10];
int row = test.length;
int col = test[0].length;2d array length in java
public static void main(String[] args) {
int[][] foo = new int[][] {
new int[] { 1, 2, 3 },
new int[] { 1, 2, 3, 4},
};
System.out.println(foo.length); //2 // gives count of rows
System.out.println(foo[0].length); //3 // gives count of columns for particular row
System.out.println(foo[1].length); //4
