Primitive values and references 2)What does the statement Dog myDog=new Dog( ) : represent? A. Instantiation and assignment of a Dog object B. Creation of a primitive type variable C. Reassignment of an existing Dog reference D. Declaration without initialization of myDog Why is it important to initialize instance variables in a constructor? A. To ensure methods can be called without errors B. To improve performance of the application C. To automatically allocate memory for the variable D. To avoid default values like null or 0 4)In a Java application the PetShop class has a method called trimFur()that requires a specific instance of the Dog class as a parameter During execution, an instance named effie is passed to method from the main application class.

Answer 1

1) What type of value can a variable store in Java? D. Primitive values and references Explanation: In Java, variables can store either primitive data types (such as int, char, and boolean) or references to objects (instances of classes). 2) What does the statement Dog myDog = new Dog(); represent? A. Instantiation and assignment of a Dog object Explanation: The statement creates a new instance of the Dog class and assigns it to the variable myDog. 3) Why is it important to initialize instance variables in a constructor? D. To avoid default values like null or 0 Explanation: Initializing instance variables in a constructor ensures that they have a specific value, avoiding default values like null or 0, which may not be suitable for the application. 4) In a Java application, the PetShop class has a method called trimFur() that requires a specific instance of the Dog class as a parameter. During execution, an instance named effie is passed to the method from the main application class. Why does the "trimFur" method need a Dog instance? A. To know which dog's fur to trim Explanation: The trimFur method needs a Dog instance to know which specific dog's fur to trim. Without passing the instance, the method would not know which dog's fur to modify. 5) In a Java program, a class named Dog has an instance variable called name. A method within the same class assigns a local variable tempName to Buddy and then sets name equal to tempName. The program later prints the value of name. What will be printed as the value of 'name'? A. tempName Explanation: The value of 'name' will be assigned the value of 'tempName' because the method sets name equal to tempName. Therefore, when the program prints the value of 'name', it will print the value of 'tempName'.
