Entry level: 2 classes and Exception in thread "main"

[y0zh]

Hi All,

Please kindly help me to identify the problem, I use Eclipse IDE

public class Emp {
 
	private String name;
	private String jobTitle;
 
	public void setName(String nameIn){
		name=nameIn;
			}
 
	public String getName(){
		return name;
	}
 
	public void setTitle(String TitleIn){
		jobTitle=TitleIn;
	}
	public String getTitle(){
		return jobTitle;
	}
 
	public void cutCheck(double amountPaid){
		System.out.println("Pay to the order ", name);
		System.out.println("***$", jobTitle);
		System.out.println("",amountPaid);
	}
 
}

import java.util.Scanner;
import java.io.File;
import java.io.IOException;
 
 
public class TestClass {
 
	public static void main(String args[])
								throws IOException{
		Scanner diskScanner=new Scanner(new File("emp.txt"));
 
		for (int empNum=1; empNum<=3;empNum++){
			payOneEmp(diskScanner);
		}
	//	diskScanner.close();
	}
 
               static void payOneEmp(Scanner aScanner) {
		Emp anEmp=new Emp();
 
		anEmp.setName(aScanner.nextLine());
		anEmp.setTitle(aScanner.nextLine());
		anEmp.cutCheck(aScanner.nextDouble());
		aScanner.nextLine();
 
	}
 
}

Exception in thread "main" java.util.NoSuchElementException: No line found

at TestClass.payOneEmp(TestClass.java:21)

The Scanner class's nextLine() method called on line 21 did not find a line to read.
Make sure there are enough lines in the file
or use the Scanner class's hasNextLine() method to test for a line before trying to read it.

do you have an idea what kind of structure should be a file to make it readable?
I tried to fill in the file based on typed in method cutCheck, but got

Exception in thread "main" java.util.NoSuchElementException
at java.util.Scanner.throwFor(Unknown Source)

The Scanner class should be able to read most text files.
I don't know what "typed in method cutCheck" means.
You should be able to create the file to be read with any text editor.

Try debugging the code by adding a println() statement after every statement that reads from the file. Have the println() statement print out what was read. That will allow you to see what the program is doing.
