Help w/ private methods program..

Question

hi guys...
i was just wondering if somebody can help me w/ the code i am writing for a project..
the project is about prime numbers and its factors.
-we have to create a private method called checkInput() which is sent the users String inputted number as a parameter and returns a boolean indicating wether the input is valid or not. (I am using inputNum as the variable that holds the number)
-also i have to call that checkInput private method from some other private method, which giving me errors when compiling...
thanks a lot...
private void getInput()throws IOException
BufferedReader stdin = new BufferedReader
(new InputStreamReader(System.in));
System.out.print("Enter an INTEGER number greater than "+MIN+". ");
while (inputNum <= 1)
System.out.print("Enter an INTEGER number greater than "+MIN+". ");
inputNum= Integer.parseInt(stdin.readLine());
}//end of while loop
checkInput();
}//end of method getInput.
// This method is to send the users String inputted
// number as a formal parameter and returns
// a boolean indicating whether the input is valid
// or not.
private boolean checkInput(String inputNum)
while(inputNum != null)
return true;
}///end of checkInput method.
// This method is to pass a formal parameter number
// which is a valid integer number that the user
// entered. The method will return a Boolean
// value indicating whether the number is a prime.
private boolean IsPrime (int number)
if (number == 1 || number == 2)
return true;
for (int i=2; i<(int)(number/2); i++)
if ( (number/i)==(int)(number/i) )
return false;
return true;
}//end of method IsPrime.
// This method calls the IsPrime method passing
// it the actual parameter inputNum which is
// valid user inputted number.
private void checkForPrime ()
IsPrime(inputNum);
if(true){
System.out.println(inputNum+ " is a prime");
}else
System.out.println(inputNum+ " is not a prime");
printAllFactors(inputNum);
}// end of checkForPrime method.
// This method prints out "Its factors are:",
// skips a line and then prints out all the factors
// of the formal parameter number.
private void printAllFactors (int number)
System.out.println("Its factors are: ");
System.out.println();
for (int i = 2; i <= number; i++){
if(inputNum % number == 0)
System.out.println(number + " is a factor.");
break;
System.out.println(number + " is not a factor.");
}// end of printAllFactors method.
}// end of main class.this is the code i have so far...

Please don't crosspost. It cuts down on the effectiveness of responses, leads to people wasting their time answering what others have already answered, makes for difficult discussion, and is generally just annoying and bad form.
