how to get the length of a jagged array java

To get the length of a jagged array in Java, you can use the length field of the array to get the number of rows in the array, and then use the length field of each row to get the number of columns in that row.

A jagged array is an array of arrays, where each row can have a different number of columns. Here's an example of how you can get the length of a jagged array in Java:

int[][] numbers = {{1, 2, 3}, {4, 5}, {6, 7, 8, 9}};
int rows = numbers.length;
int columns = 0;

for (int[] row : numbers) {
    columns += row.length;
}

In this example, the numbers array is a jagged array containing three rows, with three, two, and four columns, respectively. The rows variable holds the number of rows in the array, and the columns variable holds the total number of columns in all rows.

You can use a loop to iterate over the rows of the array and get the length of each row.
