Java homework, multiple classes and methods 1

Superb youtube tutorial link: http://www.youtube.com/watch?v=Hl-zzrqQoSE&feature=PlayList&p=FE2CE09...

PG 126, 3.14, Create a class called Employee that includes three pieces of information as instance variables--a first name (type String), a last name (type String) and a monthly salary (double). Your class should have 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, set it to 0.0. Write a test application named EmployeeTest that demonstrates class Employee's capabilities. Create two employee objects and display each object's yearly salary. Then give each Employee a 10% raise and display each Employee's yearly salary again.

"When I tried to use the lower case version I wasn't able to use it in an if statement" How did you use it? Did you use like if(double1 == doubl2){ } or did you do if(double1.equals(double2)){ } the == just compares memory addresses when you are comparing data types the equals method compares values.

I just used the captalized Double.

Double ==Double

I don't know how you can use the lower case, another thing you can try is casting it from a double to Double. The syntax would look like this

(Double)double1variable ==(Double)double2variable.

I think that could work, let me know

I'm not in your class, I'm just some random person :p

@miamimanni Double is an object, like Integer as opposed to the primitives int and double.

Hey, out of luck my friend =/

I just finished up my associates degree fulfilling my last 2 requirements of astronomy, and biology. The semester before I was doing XML, operating systems, and some other class (nothing to do with programming).

I'm afraid to say the least that I'm too rusty =/

Right now I'm trying to re-cap myself on VBA because I got a project to implement at work, and VBA works pretty good with excel.

Take care my friend and good luck,

Manni
