//global variables
int tempNum; //holds number as it's read
int numPrime; //increment by 1 each time a prime is found

//loop to read in numbers until end of file is reached
while(file.hasNext()){

   //read in number (integer in this example) and store in variable temporarily
   tempNum = file.nextInt();

   //conditional statement (if statement) to check for prime numbers
   if(tempNum % 2 == 0){
      //number is prime, since the number divided by 2 does not produce a remainder
      //so we will increment the "numPrime" variable by 1
      numPrime++;
   }
