Define a class to accept the elements of an array from the user and check for the occurrence of positive number, negative number and zero.
Example
Input Array: 12, -89, -56, 0, 45, 56
Output:
3 Positive Numbers
2 Negative Numbers
1 Zero
Answer
import java.util.Scanner;
public class KboatSDANumbers
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
int pc = 0;
int nc = 0;
int zc = 0;
System.out.print("Enter size of array : ");
int l = in.nextInt();
int arr[ ] = new int[l];
System.out.println("Enter array elements : ");
for (int i = 0; i < l; i++) {
arr[i] = in.nextInt();
}
for (int i = 0; i < l; i++) {
if (arr[i] < 0)
nc++;
else if(arr[i] > 0)
pc++;
else
zc++;
}
System.out.println(pc + " Positive Numbers");
System.out.println(nc + " Negative Numbers");
System.out.println(zc + " Zero");
}
}Output

Define a class to accept a number and check whether the number is valid number or not. A valid number is a number in which the eventual sum of digits of the number is equal to 1.
e.g., 352 = 3 + 5 + 2 = 10 = 1 + 0 = 1
Then 352 is a valid number.
