Else without if error

[Kevin Quarles]

I am getting the following error: c:\Projects>javac PayrollProgram2.java
PayrollProgram2.java:30: 'else' without 'if'
else

This payroll program has to be modified so it continues to request employee information until the user enters stop as the employee name. I also have to program the application to check that the hourly rate and number of hours worked are positive numbers. If either the hourly rate or the number of hours worked is not a positive value, the application should prompt the user to enter a positive amount.

   //PayrollProgram2.Java
//By: me

import java.util.Scanner;  // Program uses class scanner

     public class PayrollProgram2
{

     // main method begins execution of Java application

      public static void main( String args[] )
{
// create Scanner to obtain input from command window
Scanner input = new Scanner( System.in );

int number1; // hours worked
int number2; // hourly pay rate
int sum; // total of hours worked multiplied by hourly pay rate

system.out.println ( "Enter the employee's full name: " ); // prompt
String theName = input.nextLine(); // read a line of text
Payroll.setEmployeeName( theName ); // set the employee name

if(theName != "Stop");
{
system.out.println( "Enter total hours employee worked: " ); // prompt
number1 = input.nextInt(); // read first number from user
}

else
system.out.println( "Re-enter employee's full name: "); //prompt

if(number1 >= 0)
{
system.out.println( "Enter hourly pay rate: " ); // prompt
number2 = input.nextInt(); // read second number from user

}
else
system.out.println( "Please enter a positive number: ");// prompt

if(number2 >= 0)
{

sum = number1 * number2; // multiply hours worked * hourly pay rate

system.out.println( "Employee Name:,Weekly pay is $ %d\n", sum );

// display employee name and weekly pay total

}
else
system.out.println("Enter a positive number: ");// prompt

} // end method main

} // end class PayrollProgram2 

I just do not understand why I am getting this error. Can you please help?

You have an extra semi-colon on line 24.

When I remove the semi colon from line 24, I now have 8 errors, which are the following:

system.out.println ( "Enter the employee's full name: " ); // prompt

Kevin:

You may be looking for the System class. Remember that in Java case matters.

Also, this isn't a case of -- you cause those errors when you removed the semicolon. What happened is that the semicolon cause an error that obfuscated the other errors. So, when you fixed the semicolon error, the other errors showed up.

Fixing the semicolon was correct. Now you need to fix the rest.

Now I am getting more errors:

PayrollProgram2.java:22: cannot find symbol
symbol : variable Payroll
location: class PayrollProgram2
Payroll.setEmployeeName( theName ); // set the employee name
^
PayrollProgram2.java:47: cannot find symbol
symbol : method println(java.lang.String,int)
location: class java.io.PrintStream
System.out.println( "Employee Name:,Weekly pay is $ %d\n", sum );
^
2 errors

Am I putting in the wrong symbols here? My text book seems the same.

Kevin:

For the second error, the println() method does not behave like C/C++'s printf(). Check the API for PrintStream (System.out is an object of class PrintStream) for a very similar method. For the first error, you may need to do an import, or check the method signature to get that to work.

I am not sure what I am supposed to do here.

For the first error, what am I supposed to import?

For the second error, I am not following what you are saying.

I am assuming by the way you are responding that this is not a simple problem?

[Henry Wong]

For the first error, what am I supposed to import?

You have to tell us. The compiler doesn't know what to do with "Payroll". What is that? Is it a variable? If it is, then you need to declare it somewhere. Is it another class? If it is, then you have to import it. We can't tell you exactly what to do, since we don't know what you are trying to use.

For the second error, I am not following what you are saying.

Basically, there is no such a thing as a println() method that takes a string and an int. Perhaps you want to use the printf() method?

If you wrote the code, I suggest writing a little at a time and resolving errors as you see them. That's better than typing a lot of code, and dealing with many errors at a time. Whether or not you wrote it, it looks like you should start out with something simpler.

As far as your errors go, just take them one at a time. For example, "cannot find symbol... Payroll" means the compiler encountered the symbol "Payroll" but couldn't find where it was declared. What is Payroll? If it's another class you've defined, you either need to qualify that reference with its package name, or use the "import" keyword and specify the package there. The "package system does not exist" is probably caused by the dot notation in "system.out.println..." -- since there is no variable "system" in scope, I guess it's trying to interpret that as a package name. You probably mean to use "System.out.println..." -- "out" is a public field defined in class System, and its data type has a println() method.

But again, if you're trying to learn Java, I'd start with a simple "Hello World" example, and go from there.

If I do an import, that would not be on that line, right?

I'm not sure what you're asking here.

Kevin:

Look at line 4 of the code you posted. That should help with import placement.

[fred rosenberger]

The first time the word "Payroll" appears in your program (and not as a comment) is on line 24. You have not declared it as a variable and it is not part of the Scanner class (which you DID import)...So the compiler has NO IDEA what that is. It can't figure it out.

Neither can we.

If this is a PayrollProgram2 , do you have a working PayrollProgram1 you could reference to see how it got a Payroll object?
