Question

Create a new Java program called Flip. Write code that creates and populates an array of size 25 with random numbers between 1-50. Print the array. Print array in reverse.

We use bluej for our JAVA program. If you can help id greatly appreciate it.

PROGRAM

/* package to use random number */
import java.util.Random;
public class Flip
{
public static void main(String[] args)
{
int i;
       /* array of size 25 */
       int arr[]=new int[25];
       /* create object rand of class Random */
       Random rand = new Random();
       for(i=0;i<25;i++)
       {
       /* take 25 random numbers 1 to 50 */
       arr[i]=rand.nextInt((50 - 1) + 1) + 1;
       }
       /* print array */
System.out.println("\nArray is :\n ");
for(i=0;i<25;i++)
       {
System.out.print(arr[i] + " ");   
}
       /* print array in reverse order */
System.out.println("\n\nArray in reverse order is :\n ");
for(i=24;i>=0;i--)
       {
System.out.print(arr[i] + " ");   
}
System.out.println();      
}
}

SCREEN SHOT

/* package to use random number */ import java.util.Random; public class Flip I { public static void main(String[] args) int i; /* array of size 25 */ int arr[]=new int [25]; /* create object rand of class Random */ Random rand = new Random(); for(i=0;i<25;i++) { /* take 25 random numbers 1 to 50 */ arr[i]=rand.nextInt ((50 1) + 1) + 1; /* print array */ System.out.println("\nArray is : \n"); for(i=0;i<25;i++) System.out.print (arr[i] + " "); /* print array in reverse order */ System.out.println("\n\nArray in reverse order is :\n"); for(i=24;i>=0;i--) System.out.print (arr[i] + "); System.out.println(); }

OUTPUT

: Array is 35 23 33 39 22 1 49 4 37 8 26 6 4 37 19 21 23 27 3 31 20 8 46 20 28 Array in reverse order is : 28 20 46 8 20 31 3 27 23 21 19 37 4 6 26 8 37 4 49 1 22 39 33 23 35
