Question

Write a piece of code that constructs a two-dimensional array of integers with 5 rows and 10 columns. Fill the array with a multiplication table, so that array element [i][j] contains the value i * j. Use nested for loops to build the array.

java Program

Answer 1

public class MultiplicationTable {

    public static void main(String[] args) {
        int[][] array = new int[5][10];
        for (int i = 0; i < array.length; i++) {
            for (int j = 0; j < array[i].length; j++) {
                array[i][j] = i*j;
            }
        }

        // print array here
        for (int i = 0; i < array.length; i++) {
            for (int j = 0; j < array[i].length; j++) {
                System.out.print(array[i][j] + "\t");
            }
            System.out.println();
        }
    }
}
