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 are using blueJ for my java class, if you can help me id greatly appreciate it.

Answer 1

Source Code:

class blueJ
{
   public static void main(String[] args) {
       int[] arr=new int[25];
       int max=50,min=1,i=0;
       for(i=0;i<25;i++)
       {
           arr[i]=(int)(Math.random()*(max-min+1)+min);
       }
       System.out.println("Array Elements:");
       for(i=0;i<25;i++)
       {
           System.out.print(arr[i]+" ");
       }
       System.out.println();
       System.out.println("Array Elements in Reverse order:");
       for(i=24;i>=0;i--)
       {
           System.out.print(arr[i]+" ");
       }
       System.out.println();
   }
}

2 class blue] 3 { public static void main(String[] args) { int[] arr=new int [25]; int max=50,min=1,i=0; for(i=0;i<25;i++) { } arr[i]=(int) (Math.random() *(max-min+1) +min); System.out.println("Array Elements:"); for(i=0;i<25; i++) { 9 10 11 12 13 14 15 16 17 18 19 20 System.out.print(arr[i]+" "); } System.out.println(); System.out.println("Array Elements in Reverse order:"); for(i=24;i>=0;i--) { } System.out.print(arr[i]+" "); 21 22 System.out.println(); } 23 24 }
