CSA Unit 5

3. local variable in a method header that holds the data sent in
5. keyword which indicates that other classes have access to the method
7. a modifier used when declaring variables so other code in other classes can’t change their values
8. methods which do not have a return statement
11. arguments and parameters must _________ in type and number
13. a void method which changes or mutates a private variable
15. the job of breaking a problem into smaller problems and writing methods for each sub-problem
17. when the address of the actual parameters is passed to the function as the formal parameters and both refer to the same location in memory
19. when we have multiple methods of the same name in one class that have different number and order of parameters
21. when we create a new space in memory to hold a reference to an object
22. data stored in memory directly and if changes are made by a method, they are not preserved
24. when each constructor calls another, which in turn calls mutator methods

1. to make it possible for another class or user to use the class without revealing how everything is done
2. when the values of actual parameters are copied to the function’s formal parameters and there are two copies of parameters stored in different memory locations
4. a constructor added by Java has no parameters and sets all the member variables to default values
6. a value that does not change
9. data stored as references, if they are changed in a void method those changes are preserved
10. something that changes the behavior of variables or methods
12. a method that lets you access a variable from an object
14. a statement to send a value back to the calling method and thus provide output which can be stored as a variable
16. a construct to represent the behaviors of classes
18. a modifier which means only one copy exists for all objects of that class and all objects of this class share access to the entity
20. data values sent to a method
23. a construct used to represent the fields of classes
