1.) A class and its members can be described graphically by using UML (Unified Modeling Language).
2.) Most of Java’s built-in operation do not apply to classes. You cannot perform arithmetic operations on class objects.
3.) Precondition: A statement specifying the condition(s) that must be true before the function is called.
Postcondition: A statement specifying what is true after the function call is completed.
1.) What is a client of a class?
2.) What is the “member access operator”?
1.)I’m fairly confident in my knowledge of this stuff and I look forward to using this stuff in labs.
1. Shallow copying is two ore more refernces variables of the same type point to the same object.
2. A way to prevent shallow copying is to have th eoject being copied create a copy of itself, and than return the address, that is, the refences of the copy.
3.a program or software that uses and manipulates the objects of a class is called a client of that class.
1. When do we use pre and post conditions?
2. What would happened if we used shallow copying?
1. This section was alot of code that I belived was written very well and I think that I understand it quite well.
1) Once a class is defined you can declare reference variables of that class.
2) Most of Java’s built in operations do not apply to classes.
3) A referance variable has the same scope as other variables.
1) Do programmers generally use shallow or deep copying more often?
2) What exactly is scope?
1) This section, like everything else we’ve done, goes along with everything we’ve been doing.
1.Once a class is defined, you can declare reference variables of that class.
2.The dot . (period) is called the member access operator in java.
3.Shallow copying is a common mistake, especially by beginning Java programmers.
1.Can one clock pull data from another clock.
2.What is class scope.
1.Clocks are a bit difficult to understand but will be a fun program to work with.

1. Clock has 3 instance variables Hours Minutes and seconds
2. deep coping is when the variable refers to its own object
3. reference variables can be passed as parametersto method s and returned as method values
1. is deep coping better then shallow coping
2. will we use one more than the other
this is kinda ok

1. The dot . (period) is called the member access operator.
2. Declaring reference variables such as Clock myClock does not allocate memory spaces to store the hours, minutes, and seconds.
3. The number of arguments and their type should match the formal parameters (in the given order) of one of the constructors.
1. Is there a time where you would want to use shallow copying over deep copying?
2. Do you have to leave comments that specify the preconditions and postconditions?
1. The example in the book helped me better understand what they were telling me and I believe that i have a better understanding then I had prior.
