This keeps popping up

Here's the code for the things that need javadocs

```

public class Lab2 {

public static void main(String[] args)
{

System.out.print ("enter first numerator ");
int num1 = input.nextInt();//take in next input
int denom1=0;//initilize denominator to zero
while (denom1 == 0) //set a determined condition for so long as there is no input
{
System.out.print ("enter first denominator "); //prompt for input of a denominator
denom1 = input.nextInt();//input for next denominator
}
System.out.print ("enter second numerator " );//prompt for another numerator
int num2 = input.nextInt();//for accepting the next numerical input
int denom2=0;//denominator condition set to zero
while (denom2 == 0) //set a determined condition for so long as there is no input for the second denominator
{
System.out.print ("enter second denominator " );//display the prompt message
denom2 = input.nextInt();//
}
Fraction firstfrac = new Fraction(num1,denom1); //this creates an object using the first fraction class
Fraction secndfrac = new Fraction (num2,denom2);//this creates an object using the second fraction class
firstfrac.display();//display first fraction
secndfrac.display();//display second fraction
int denomsum=firstfrac.getDenominator()*secndfrac.getDenominator() ;
int numersum=(firstfrac.getNumerator()*secndfrac.getDenominator())
+(secndfrac.getNumerator()*firstfrac.getDenominator());

System.out.print("The sum of both fractions is ");
sumfrac.display();

What's wrong in these?.Sorry for sounding so frank -_- it's late now.Thanks everyone.
