This keeps popping up

Here's the code for the things that need javadocs

```

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
}

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

}
Fraction firstfrac = new Fraction(num1,denom1); //this creates an object using the first fraction class

firstfrac.display();//display first fraction
secndfrac.display();//display second fraction

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