Why do I keep on getting the "exception in thread "main" java.lang.nosuchmethoderror: main" error?

See more:

I have written a code using External Methods.

The code compiles successfully.
Once I run the Application it prompts me the following:
"Exception in thread "main" java.lang.NoSuchMethodError: main"

I can't see what I'm doing wrong.

What I have tried:

import java.io.*;

public class Employee
{
	String FirstName;
	String LastName;
	String Position;
	float Rate;
	float Hours;

	public Employee(String f, String l, String p, float r, float h)
    {
        FirstName = f;
        LastName = l;
        Position = p;
        Rate = r;
        Hours = h;
    }
    public Employee(String f,String l, String p)
    {
		LastName = l;
        FirstName = f;
        Position = p;
    }
    public String getFirstName()
    {
        return FirstName;
    }
    public String getLastName()
    {
        return LastName;
    }
    public String getPosition()
    {
        return Position;
    }
    public float getRate()
    {
        return Rate;
    }
    public float getHours()
    {
        return Hours;
    }
}

I am not sure what you mean by "I have written a code using External Methods."

However, you get that message because there is no main method in your class, so it cannot run on its own. You need to add a main method (see below), and also the remaining code to drive this class and actually do something.

Java

// add this inside the Employee class
    public static void main(String[] args) {
        // Add code here to create objects and interface with the user.
    }

Once I do that I get the following errors:

C:\Java 1\New folder (3)\Chapter05\Employee.java:16: ')' expected
Employee(String f, String l, String p, float r, float h)
^
C:\Java 1\New folder (3)\Chapter05\Employee.java:50: ';' expected
}
^
2 errors

Tool completed with exit code 1

That looks like you have added the main method inside the constructor. I suggest you go and work through Trail: Learning the Java Language (The Java™ Tutorials)[^] to see how to do it correctly.
