Identify the logic errors. (There are 2.) What is the difference between the System.out.println() and System.out.print() methods? What is the purpose of a compiler?  a processor? Chapter 2 Describe the purpose of a constructor.  What is the difference between a default constructor and an explicit constructor?  What return type is specified for a constructor? Given the following definition statements for constructors - create a new object instance. public Dog() public Car(String inMake, String inColor, int inMPG) public House(double inLatititude, double inLongitude, String inColor) Evaluate the following statement: myAccount.deposit(payCheck); Identify the object(s), method(s), parameter(s) How many total parameters (implicit and explicit) are there? Is there an implicit parameter? If yes, what is it? Is there an explicit parameter(s)?  If yes, what is it? What makes a valid Java identifier? What are the primitive data types in Java? Which variable type would be used for the following data? GPA name age (in years) batting average football score customer address Consider the following java code: Car newCar1 = new Car("Chevy", "Blue", 32); Car newCar2 = new Car(newCar1); How many objects are created?  Are the instance variables referred to by newCar1 the same as the instance variables referred to by newCar2? Consider the following java code: Car newCar1 = New Car("Chevy", "Blue", 32); Car newCar2 = newCar1; How many objects are created? Are the instance variables referred to by newCar1 the same as the instance variables referred to by newCar2? Evaluate the following statement: public void deposit( double inAmount) Is this an accessor or mutator method?  How can you tell? Does this method return a value?  If yes, what type is the return value? Does this method accept explicit input parameters?  If yes, what type(s) is the parameter(s)? What will be the output of the following: System.out.print("COMP"); System.out.println("111"); System.out.print(" is a "); System.out.println("great class."); Reviewing each of the following variable names - do any of them violate Java syntax?  violate Java convention? tmpStation return noMore?  TmpStation  Chapter 3 Describe abstraction, encapsulation, information hiding, and black box. What is a unit test? What are javadocs?  How is a javadoc created?  What parameters can be specified for a javadoc?  What is a local variable?  What is the lifetime of a local variable? How is an implicit parameter denoted within a class? How many parameters, both implicit and explicit are in the following statements, assuming String tmpString = "Hello Class!; ? String newString = tmpString.substr(1, 3); String upperString = tmpString.upperCase(); boolean isEqual = tmpString.equals("Hello Class!"); What are the basic steps for testing a method?   How do you write an assert statement to test a method that returns an integer value?  a double value?  a string value? Chapter 4 Evaluate the following statement, assuming that initially a = 10 and b = 11. c = a + b++; What will a be equal to after this statement is executed? What will b be equal to after this statement is executed? What will c be equal to after this statement is executed? Describe final and static with regards to defining variables. Define a constant variable with a name of MINS_PER_HR set equal to the value 60. What is an instance variable?  Should an object be manipulated by directly accessing its instance variables? What is the lifetime of an instance variable? What will be the result of the following equation? 3 + (4 % 2) - 6 / 4 Assuming that you need to generate a class and objects to represent the following - what class would be needed and how many objects should be created of each. orange - 15 oranges banana - 10 bananas papaya - 5 papayas Evaluate each of the following statements and determine the number type.  Will the statement successfully compile? int tmpNum = 40; double tmpNum = 40.0; int tmpNum = 40.0; double tmpNum = 40; Consider the following equation: double battingAverage = 2.81; int avgRounded = battingAverage; What value will avgRounded contain?  Or will an error result?
