Help compiling a package

Question

Hello Java peeps, I have been having troubles compiling a package in Java...
My school assessment project was pretty big so I decided to cut into multiple java classes, but instead of having unclean code, I decided to add them all to one package, so i dont have to reference methods with their full names.. except now It doesnt wanna compile correctly...
Lets say I had the following:
ClassA:
package MyPackage;
public class ClassA {
SayHello() {}
ClassB:
package MyPackage;
public class ClassB {
RequestHello() {
SayHello();
The compiler will give me errors that it cant SayHello(). Why is this so?
I tried playing around with my ClassPath, the above classes are in this directory:
C:\Programming\Java\School\*.java
And its compiling as a package, ClassA goes into:
C:\Programming\Java\School\MyPackage\ClassA.class
I have set my classpath to both:
C:\Programming\Java\School\
C:\Programming\Java\School\MyPackage\
Can anyone please help me? Thanks a lot :)

Not only do your methods not have return types, but your call to SayHello() from ClassB is also incorrect. Even if the methods were defined correctly, the compiler would still not find SayHello() because it is looking for it in ClassB.
Putting them in the same package does not give you direct access. You still need to reference ClassA to get access to SayHello(). You just don't need to give it the full package name when referencing ClassA.
e.g.,
ClassA a = new ClassA();
a.SayHello();
