Executive.java, and finally MainMethod.java

Could someone please review my code? I am getting the following error: Exception in thread "main" java.lang.NumberFormatException: For input string: "��2 "

I have 4 classes plus a text file. The EmployeeClass is the super class, followed by Salesman.java, Executive.java, and finally MainMethod.java. Also attached is a word document with the project instructions. Thanks in advanced.

* and monthly salary (in dollars).

    // Instance variables
    private String employeeName;
    private int salary;

    // Default constructor to
    // initialize name and salary
    public EmployeeClass(String employeeName, int salary) {
        this.employeeName = employeeName;
        this.salary = salary;
    }

    // annualSalary method
    public int annualSalary() {
        return salary * 12;
    }

    // toString method
    public String toString() {
        String str = "Employee Name: " + employeeName + "Monthly Salary: " + salary;
        return str;
    }

    //Added later
    public int getSalary() {
        return salary;
    }
    public String getEmployeeName() {
        return employeeName;
    }
}

    // Setter method for stockPrice

        this.stockPrice = stockPrice;
    }

        if (stockPrice > 50) {

        } else {
