This question is all about Java

1. If we need to import multiple classes from different packages do we need an import line for each? Why?

2. How does dot notation differ when invoking methods & importing packages?

3. How does * work when importing packages?

4. We have to import the Scanner class in order to use its methods. Why not for String or System or Math class?

5. What package are each of the classes found in?

6. We need an object to invoke (call) the String & Scanner methods. Why don't we need to instantiate an object to invoke the Math methods?

7. List the Math methods & their parameter

For this question we will be using arrays and classes in Java to compute the min, max, and average value of items for a given array of integers. Complete the following using the base template provided below: -Create methods for min, max, and average and call them from main to print out their values. -Add a method to determine the median (http://www.mathsisfun.com/median.html) and print that value. This method is currently not in the template, so you will need to add...

1. We are all may be here for a different reason - some of us need the general education requirement, some are fulfilling a program requirement, and some may find the material interesting! Either way, I'm sure that we all come into this class with a preconceived view about the field of psychology. So...what do you think? Are psychologists just those bearded, white-haired old timers who nod at your every word while judging everything you say!? Do you have a preconceived...

At my work, we often have multiple & different components from multiple suppliers that we use to solve it down to tubing to make IV administration sets for hospitals. Each component supplier has its own unique set of dimensions where we are to bond to the tubing. We have tried to standardize the outside diameter of the tubing so that we have universal dimensions that work for three tiers of dimensions and components. It is important to take into consideration...

In this program we are going to utilize multiple classes to demonstrate inheritance and polymorphism. We will be creating a base class for our game character. The base class will be LifeForm. We will have derived classes of Human, Dragon, and Unicorn. LifeForm will have the following attributes: hitPoints – range 0 to 100 strength – range 0 to 18 You will need to provide a default constructor that initializes these attributes as follows: strength – 15 hitPoints – 100...

1) We be certain the EM wave we receive from space tell us all about the composition and the source temperature why, or why not? How the location and dynamics of celestial objects affect the observation of space? 2) Explain the process of star’s birth, burning fuel and death, main sequence, and relationship between star colors, their age and their size, black body curve, black hole, event horizon, quasar, super massive black holes, emission region, and energy released analyses. 3)

In Java In this lab we will creating two linked list classes: one that is a singly linked list, and another that is a doubly linked list ( This will be good practice for your next homework assignment where you will build your own string class using arrays and linked list ) . These LinkedList classes should both be generic classes. and should contain the following methods: Print Add - Adds element to the end of the linked list. IsEmpty...
