In Java Know the correct syntax to write a Student class: fields name and grade ; constructors; display method: include default and overloaded constructor

14

True or False 1) After a user defines his/her own constructor in a Java class, the default constructor is still available. ​___(2) Java supports multiple inheritances directly. ​___(3) Some methods in an interface can have method body.

CLASS NAME List the instance variables in the constructor. List the methods in the class. - indicates private CLASS NAME List the instance variables in the constructor. List the methods in the class. The second row of the UML diagram lists the instance variables in the constructor. For example -name: string o o name is the variable name o string is the data type of name + indicates public o getName is the method name o o string is the return data type Java.util. The third row of the diagram lists the methods in the class. For example, +getName(): string empty parenthesie indicate nothing is sent to the method.

Java A class always has a constructor that does not take any parameters even if there are other constructors in the class that take parameters. Choose one of the options:TrueFalse

Classes: Write a Person class that has these attributes: person_ID, first and last names, and age Default and overloaded constructors Accessors and mutators equals method toString method (make this virtual if C++, don't forget to prep the class for polymorphism) Inheritance: Create a child class to Person called Student: Attributes: GPA and status (freshman, sophomore, junior, senior, graduate, graduated). Make sure you have appropriate accessor/mutator methods Create another child class to represent Faculty. This class will have faculty rank and length of service as attributes along with an office location. Again, add methods as needed. Application Create an application that displays a menu that allows users to add students or faculty, or print either one or exit.

True or False Constructors can accept arguments in the same way as other methods.

In order to do a range of tasks, both code and forms employ the ACTION and METHOD attributes.

Portfolio Instructions: You are working for a financial advisor who creates portfolios of financial securities for his clients. A portfolio is a conglomeration of various financial assets, such as stocks and bonds, that together create a balanced collection of investments. When the financial advisor makes a purchase of securities on behalf of a client, a single transaction can include multiple shares of stock or multiple bonds. It is your job to create an object-oriented application that will allow the financial advisor to maintain the portfolios for his/her clients. You will need to create several classes to maintain this information: Security, Stock, Bond, Portfolio, and Date. The characteristics of stocks and bonds in a portfolio are shown below: Stocks: Bonds: Purchase date (Date) Purchase date (Date) Purchase price (double)...

T/F 3. Any Java class must have a main method, which is the first method that is called when the Java class is invoked.

It is possible to express the relationship that exists between classes and objects.
