Need some java help

[Sainix]

Hey guys taking a java class and i am having trouble trying to get this to work.

need to Creat a class called Employee that includes three instance variabels, a first name (type string), a last name (type string) and a monthly salary (double). provide a constructor that initializes the three instance variables. provide a set and a get method for each instance variable. if the monthly salary is not positive, do not set its value write a test application named EmployeeTest that demonstrates class Employee's capabilities. Creat two employee objects and display each objects yearly salary. Then give each Employee a 10% raise and display each Employee's yearly salary agian.

So that is the problem and so far i have got

class Employee{

// data vector
String fn;
String ln;
double s;

// constructor
public Employee(String f, String l, double sal) {
fn = f;
ln = l;
s = sal;
}

// set procedure
void setFirst(String fNew) {
fn = fNew;
}
void setLast(String lNew) {
ln = lNew;
}
void setSal(double sNew) {
s = sNew;
}

//get function
String getFirst(){
return fn;
}
String getLast(){
return ln;
}
String getSalary(){
return s;
}
}

and for the test i have

public class EmployeeTest {
public static void main(String [] args){
Employee e1 = new Employee();
Employee e2 = new Employee("John","Pimpson",1.00);
System.out.printf("%s\t%s\t%f\n", e2.getFirst(),e2.getLast(),e2.getSalary());
System.out.printf("%s\t%s\t%f\n", e1.getFirst(),e1.getLast(),e1.getSalary());
e1.setFirst("John 5");
e1.setLast("Player");
e1.setSalary(10.00);
System.out.printf("%s\t%s\t%f\n", e1.getFirst(),e1.getLast(),e1.getSalary());
e.raiseSalary(1.1);
}
}

now im just stuck and trying to read threw my book for more info but if someone who knows java could maybe lend me a hand with this i would be greatful since this is only my first week in class.

What exactly are you stuck on?

Stuck on getting it to run, watched some youtube videos and came up with this

Public Class Employee{

// data vector
Private String firstName;
Private String lastName;
Private Double salaryValue;

// constructor
public Employee(String firstNameParameter, String lastNameParameter, Double salaryValueParameter)
{
firstName = firstNameParameter;
lastName = lastNameParameter;
if (doubleSalaryValue < 0)
salaryValue = 0.0
else
salaryValue = salaryValueParameter;
}

// set methods
void setFirstName(String firstNameParameter)
{
firstName = firstNameParameter;
}

void setLastName(String lastNameParameter)
{
lastName = lastNameParameter;
}

void setSalaryValue(Double doubleSalaryValue)
{
if (doubleSalaryValue < 0)
salaryValue = 0.0
else
salaryValue = doubleSalaryValue;

}

//get function
String getFirstName()
{
return firstName;
}
String getLastName()
{
return lastName;
}
Double getSalaryValue()
{
return salaryValue;
}


} //End Class

----------

class EmployeeTest
{
public static void main(String [] args)
{
String temp;
Double temp2;
Double temp3;
Employee EmployeeoneObject = new Employee("Bob","Bobson",10.0);
Employee EmployeetwoObject = new Employee("John","Pimpson",36.0);

temp = EmployeeoneObject.getFirstName();
System.out.print(temp);
temp = EmployeeoneObject.getLastName();
System.out.print(" ");
System.out.print(temp);
System.out.print("'s salary is ");
temp2 = EmployeeoneObject.getSalaryValue();
System.out.print(temp2);
System.out.print("/n");

temp = EmployeetwoObject.getFirstName();
System.out.print(temp);
temp = EmployeetwoObject.getLastName();
System.out.print(" ");
System.out.print(temp);
System.out.print("'s salary is ");
temp2 = EmployeetwoObject.getSalaryValue();
System.out.print(temp2);
System.out.print("/n");

temp2 = EmployeeoneObject.getSalaryValue();
temp3 = temp2 * 1.1;
EmployeeoneObject.setSalaryValue(temp3);

temp2 = EmployeetwoObject.getSalaryValue();
temp3 = temp2 * 1.1;
EmployeetwoObject.setSalaryValue(temp3);

temp = EmployeeoneObject.getFirstName();
System.out.print(temp);
temp = EmployeeoneObject.getLastName();
System.out.print(" ");
System.out.print(temp);
System.out.print("'s salary is ");
temp2 = EmployeeoneObject.getSalaryValue();
System.out.print(temp2);
System.out.print("/n");

temp = EmployeetwoObject.getFirstName();
System.out.print(temp);
temp = EmployeetwoObject.getLastName();
System.out.print(" ");
System.out.print(temp);
System.out.print("'s salary is ");
temp2 = EmployeetwoObject.getSalaryValue();
System.out.print(temp2);
System.out.print("/n");
}

}


When ever i try to javac Employee or javac EmployeeTest in command prompt i get a message saying

error: Class names, 'Employee', are only accepted if annotations explicitly requested
1 error

same thing for employeetest

Any ideas?

 

[johnlgalt]

Did you include the .java part of the file names for each file?

you gotta do javac Employee.java in order for it to compile, IIRC....

You've got a ton of typos in there. For example Private should be private and you're missing EOL delimiters in a lot of places.

One thing to do that will help TREMENDOUSLY is to get yourself a decent IDE. Have a look at Eclipse or netbeans. They do syntax checking on the fly and will save you a megaton of headaches.

I am using netbeans and i have eclipse, thank you for letting me know about that i kinda thought that might be what is up.
