When you execute the preceding program, it will ask for value to array.
You need to enter the values between the curly brackets separated by
comma as shown:
After entering the values, when you click on the OK button, following
output will appear:
Elements of mat[][] array are:
1 3 6
6 9 7
4 6 9
• Taking Values from User: As you know that the Scanner class is used to take the values form runtime. It provides
different methods to take different types of values. Let us take an example.
Program 6 Create a two-dimensional array of size 2 x 3 and print the square of all the odd numbers in the array.
1 import java.util.*;
2 class array_odd
3 {
4 public static void main()
5 {
6 Scanner sc= new Scanner(System.in);
7 int ar[][]=new int[2][3];
8 int i,j;
9 for (i=0; i<2; i++)
10 {
11 for (j=0; j<3; j++)
12 {
13 System.out.print("Enter a number : ");
14 ar[i][j] =sc.nextInt();
15 }
16 }
17 for (i=0; i<2; i++)
18 {
19 for (j=0; j<3; j++)
20 {
21 if(ar[i][j] %2==1)
22 {
23 System.out.println("Odd Number: "+ar[i][j]+ " and its square is:");
System.out.println(ar[i][j]*ar[i][j]);
