This is Java Programing

Suppose a method in the BankAccount class is defined as: .05) public double computeInterest(int rate) .06) .07) And suppose the client code has declared a BankAccount variable named acct. Which of the following would be a valid call to the above method? a) Group of answer choices b) double result = acct.computeInterest(42); acct.computeInterest(42.0, 15); d double result = computeInterest(acct, 42): e) new BankAccount(42).computeInterest0; + int result = BankAccount.computeInterest(42); How do you write a class whose objects can easily be printed on the console? a) Define a toString method in the class. b) You must provide an accessor method for every field of the object and print them individually. c) This is impossible because Java is not able to print objects. d) If your class has a print() method then you can call that method to print the objects. e) Use the System.out.printin command to print the object and it will print itself naturally. What is the difference between the public and private keywords? a) Items declared public may be seen and used from any class, while items declared private may be seen and used only from within their own class. b) Public fields can be seen in two Java programs at a time while private fields can be seen in only one Java program. c) Public members are usable only in Java, while private members are usable in other programming languages. d) A class can be public, private, or both, depending on the situation. e) The public keyword can only be used on methods, and the private keyword can only be used on fields. What items should be declared private? a) Objects' fields should be declared private to provide encapsulation, so that external code can't make unwanted direct modifications to the fields' values. b) All instance methods should be private to keep them from being called by malicious clients, for better security. c) Classes should be declared private, but methods and fields should be public. d) The most important field of a class should be private, but the other less important fields can be public. e) Fields and constructors should both always be private, but methods should always be public. .08)
