object an instance of a class class objects are created from this class describes the kind of object object represent individual instantiations of the class. method Can be invoked to communicate with objects. parameter provide additional information for a task. signature the header of a method. signature provides information needed to invoke a method. type defines what kinds of values a parameter can take. multiple instances Many similiar objects can be created from a single class. state represented by storing values in fields. method-calling objects can communicate by calling each other's methods. source code determines the structure and the behavior of each of the objects in that class. result return information from methods. field store data for an object to use. field instance variable comment inserted into the source code of a class to provide explanations to human readers. comment have no effect on the functionality of a class. constructor allow each object to be set up properly when it is first created. scope defines the section of source code from where the variable can be accessed. lifetime describes how long the variable continues to exist before it is destroyed. assignment a __________ statement stores the value represented by the right-hand side of the statement in the variable named on the left. header and body 2 parts of a method accessor method return information about the state of an object. mutator method change the state of an object. println prints its parameter to the text interval. conditional a ____________ statement takes one of two possible actions based upon the result of a test. boolean expression have only 2 possible values: true and false. boolean expression commonly found controlling the choice between the two paths through a conditional statement. local variable a variable declared and used within a single method. local variable scope and lifetime are limited to that of the method.
