Today's lab
Goals for this lab:
- write our own new classes of objects
- declare fields, methods, and constructors
- understand the difference between class code and client code
- Where you see this icon, you can click it to check the problem in Practice-It!
Declaring a class (syntax)
public class ClassName {
// fields
fieldType fieldName;
// methods
public returnType methodName() {
statements;
}
}
A couple things look different than programs for past homeworks:
- no
main method. It won't be run like a client program.
- methods don't have the
static keyword in the header.
- variables declared outside of any method (fields) are visible in every method.
