Question
Write a class called ArrayRecap which has a main method. Inside the main method: - Create an array of integers of size 10 called intArray - Using a for loop, repeat the following 10 times o Ask the user to enter an integer o Store the number into the intArray - SOP the contents of this array using Arrays.toString ( You will need to import a class!) - Write a second loop that displays the values in the intArray in the opposite order from which they were entered and computes their decimal average. - Display the decimal average of the numbers entered.
Explanation / Answer
public class ReverseArray {
public static void main(String[] args) {
int arr[]=new int[10];
int j=0;
int k;
int temp;
int a,b;
double decimaval=0;
Scanner read =new Scanner(System.in);
for(int i=0;i<10;i++)
{
j=i+1;
System.out.println("Please enter "+ j + " value");
arr[i]=read.nextInt();
}
System.out.println("Entered values::");
for(int i=0;i<10;i++)
{
System.out.println(""+arr[i]);
}
System.out.println("Reverse values::");
j = 10 - 1; // now j will point to the last element
int i = 0; // and i will point to the first element
int t=0;
while(i<j)
{
temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
i++;
j--;
}
System.out.print("Now the Reverse of Array is : ");
for(i=0; i<10; i++)
{
t+=arr[i];
System.out.print(arr[i]+ " ");
}
decimaval=t/10;
System.out.println("");
System.out.println("decimal value:::::::"+decimaval);
}
}
Expected output
===============
Please enter 1 value
1
Please enter 2 value
2
Please enter 3 value
3
Please enter 4 value
4
Please enter 5 value
5
Please enter 6 value
6
Please enter 7 value
7
Please enter 8 value
8
Please enter 9 value
9
Please enter 10 value
10
Entered values::
1
2
3
4
5
6
7
8
9
10
Reverse values::
Now the Reverse of Array is :
10 9 8 7 6 5 4 3 2 1
decimal value:::::::5.0
