New to Java

I'm supposed to be creating a program that will calculate weekly pay for an employee after the user inputs the employee's name, pay rate, and hours worked that week. Keep in mind, I really don't understand much of what I'm doing yet (this is only my second assignment). If anyone can find what's wrong and help me adjust it, I would greatly appreciate it.

Here is my code:

// FinalWeek2.java
// Program that calculates weekly pay for an employee
import java.util.Scanner;

public class FinalWeek2
{
public static void main( String args[] )
{
Scanner input = new Scanner( System.in );

int number1; //adds hourly rate
int number2; //adds hours worked
int product; //product of number1 and number2

//Name Input
System.out.print( "Enter name of employee (Type 'stop' when you are done): " );
String nameOfEmployee = input.nextLine();
if ( nameofEmployee = "stop" ){
}

//Pay Input
System.out.print( "Enter pay per hour (Type 'stop' when you are done): " );
number1 = input.nextInt();
if ( number1 < 0 ){
System.out.println( "Please enter a positive number: " );
} else
if ( number1 = "stop" ){
}
//Hours Input
System.out.print( "Enter hours worked (Type 'stop' when you are done): " );
number2 = input.nextInt();
if ( number2 < 0 ){
System.out.println( "Please enter a positive number: " );
} else
if ( number2 = "stop" ){
}

product = number1 * number2;

System.out.println();
System.out.printf( "earned $ %d\n this week", product );

}

}







Here are the errors I'm getting:
