Java program that computes proper divisors af an integer?

Answer 1

,

this answer is not perfect, its logic is correct. Validation for a floating point number has to be done. Change the code urself..

import java.io.*;

class proper

{

public static void main(String args[])

{

try

{

System.out.println("Enter the number");

InputStreamReader isr = new InputStreamReader(System.in);

BufferedReader br = new BufferedReader(isr);

String str = br.readLine();

int n = Integer.parseInt(str);

int b[]=new int[n];

if(n>0)

{

for(int i=1;i

{

if(n%i == 0)

{

b[i]=i;

}

}

System.out.print("Proper divisors of " + n + " are");

for(int i=1;i

{

System.out.print(b[i]);

}

}

else

{

System.out.println("please enter a positive number");

}

}catch(Exception e)

{

System.out.println("Caught exception " + e);

}

}

}
