2. Create a class with main() method

3. In main() method create an Array with given set of values

4. initialize i variable for index

5. use for loop till the index i.e i will be a last index

6. In for loop display array with each index value.

7. End

Code:

import java.util.*;
class forsample
{
   //main method
   public static void main(String[] args) {
   int i; //for index
   int arr[]={1,3,5,7,9};//create an array with given values
   System.out.println("The values are:");
   for(i=0;i<arr.length;i++)//for loop for display array values
   {
       System.out.println(arr[i]);
   }
   }
}

Output:
