Write a program in Java to accept 10 different numbers in array and calculate the sum and average of all Palindrome numbers present in that array using function.
Instance variables/Data members:
int a [ ] : to store the 10 numbers
Rest of the variables can be assumed as required according to the logic of the program.
Instance Methods:
void accept ( ) : to accept 10 numbers in an array using an input statement.
boolean check (int x) : to check the argument is Palindrome number or not. If yes returns true otherwise returns false.
void display ( ) : to display all the Palindrome number and their position in that array. Finally display their sum and average with proper message.
Write a main ( ) to call the method using an object to perform the task.
import java.util.Scanner;
class Disha
{
int a[] = new int[10];
void accept()
{
Scanner sc = new Scanner(System.in);
System.out.println("ENTER 10 NUMBERS");
for(int i=0; i<10; i++)
{
a[i]=sc.nextInt();
}
}
boolean check(int x)
{
//reverse the number
int temp=x, rev=0;
while(temp!=0)
{
int dig=temp%10;
rev=rev*10+dig;
temp/=10;
}
if(x == rev)
return true; //It is palindrome
else
return false; //It is not Palindrome
}
void display()
{
int sum=0, count=0;
double avg;
System.out.println("PALINDROME ELEMENTS \t POSITION");
for(int i=0; i<10; i++)
{
//if the array element is palindrome
if(check(a[i]))
{
System.out.println(a[i] + "\t\t\t" + (i+1));
sum+=a[i]; //add element to sum
count++;
}
}
avg=sum/count;
System.out.println("SUM OF ELEMENTS = " + sum);
System.out.println("AVERAGE OF ELEMENTS = " + avg);
}
public static void main(String args[])
{
Disha obj = new Disha();
obj.accept();
obj.display();
}
}
