Answer:
public class array{
public static void main(String []args){
int[] array = {2,4,7,1,9};
int num_vals = array.length;
for(int i=0;i<num_vals;i++){
System.out.println(array[i] + " ");
}
for(int i=num_vals-1;i>=0;i--){
System.out.println(array[i] + " ");
}
}
}
Explanation:
First create the class in the java programming.
Then create the main function and declare the array with values.
Store the size of array in num_vals variable by using the function array.length.
create a for loop to iterate the each element in the array and then print on the screen with spaces and newline.
it traverse the loop from first to last.
Then, again create the for loop to iterate the each element in the array and then print on the screen with spaces and newline but the traversing start from last to first.
