Consider the proper Java programming techniques shown in class, which of the following classes cannot be extended? All of these classes are allowed to be extended so none of the answers are correct abstract class A{} class A{ private A();} O All of these classes cannot be extended class A{} O public class A{} final class A{} class A{ protected A();} When programming in Java, you will get a compile error if a method in a subclass has the same signature as a method in a super class since the subclass will extend the superclass and all the methods will be available in the subclass. O True O False Using the keyword to resolve conflicts between method parameters and instance fields/methods of the invoked class is a technique commonly used in Java. try if new O super None of the answers are correct void this When programming in Java, the programmer should make each method have a unique name when they are located in the same class otherwise there will be an error. This is a common naming convention standard that every Java programmer knows about. True False When writing code, a subclass is located in a different package than the superclass. The programmer wants to allow the subclass to access a method defined in the superclass. Which access modifier(s) can be used for this method? public only protected only None of the answers are correct no modifier (default) only O private, public and protected only public and no modifier (default) O public and protected only When writing code, a subclass is located in a different package than the superclass. The programmer wants to allow the subclass to access a method defined in the superclass. Which access modifier(s) can be used for this method? public only protected only None of the answers are correct no modifier (default) only O private, public and protected only public and no modifier (default) O public and protected only When programming in Java, the programmer should make each method have a unique name when they are located in the same class otherwise there will be an error. This is a common naming convention standard that every Java programmer knows about. True False What is the difference between 'double' and 'Double' in Java? O None of the answers are correct O They both hold real numbers with decimal values, they are just spelled differently double and Double are both objects where double is 32 bits and Double is 64 bits O Double is primitive data type and double is an object O double is an interface and Double is a class double is an object and Double is a class O In Java, data types are not case sensitive, therefore they are both the exact same O There is no difference. They are equivalent. double is a primitive data type and Double is a class
