I have a class file with my method to read for prime numbers in my text document, and then my main java file calls on it using the file input code. I am lost in my code, and not sure what is going wrong, because it just reads out 0 for each line read right now. The text document has 5 rows, with the numbers 3, 5, 7, 11, 13, so it should read out that each line is prime, not "0".
Here is my main
import java.util.Scanner;
import java.io.*;
//import TwoNumber.TwoNumber;
import OneNumber.OneNumber;
public class Ch5Lab {
public static void main(String[] args) throws IOException
{
OneNumber object1;
//TwoNumber object2;
int num1= 0;
object1 = new OneNumber();
//Creates scanner object for keyboard input
Scanner keyboard = new Scanner(System.in);
//Get the input filename
System.out.print("Enter the filename to open: ");
String filename = keyboard.nextLine();
//Open the file;
File file = new File(filename);
Scanner inputFile = new Scanner(file);
object1.setIsPrime(num1);
//Reads & checks for prime number
String line = inputFile.nextLine();
int n;
n = Integer.parseInt(line);
for(n = 1; n<=5; n++)
{
System.out.println(object1.getIsPrime());
}
//Close the file
inputFile.close();
System.out.println("Data written to file.");
}
}
Here is my OneNumber class
package OneNumber;
public class OneNumber
{
static int value;
public OneNumber()
{
}
public OneNumber(int value1)
{
value = value1;
}
public void setIsPrime(int value1)
{
int num = 0;
for (value1 = 2; value1 <= num; value1++)
{
int check = 1;
for(int b = 2; b < value1; b++)
{
check = check * (value1 % b);
System.out.print("Prime");
}
if(check!=0)
System.out.print("Not Prime");
}
}
public int getIsPrime()
{
return value;
}
