How would I get this java code to work and with a main class that would demo the rat class?

class rat {
    private String name;
    private String specialAbility;
    private int TotalHealth;
    private int shieldedHealth;
    private int cooldown;

    public rat()
    {
    }
    public rat(String n,String SA,int TH,int SH,int cd)
    {
        name=n;
        specialAbility=SA;
        TotalHealth=TH;
        shieldedHealth=SH;
        cooldown=cd;
    }
    public void setname(String n)
    {
        name=n;
    }
    public String getname()
    {
        return name;
    }

    public void setability(String SA)
    {
        specialAbility=SA;
    }

    public String getability()
    {
        return specialAbility;
    }

    public void sethealth(int TH)
    {
        TotalHealth=TH;
    }
    public int gethealth()
    {
        return TotalHealth;
    }
    public void setsh(int SH)
    {
        shieldedHealth=SH;
    }
    public int getsh()
    {
        return shieldedHealth;
    }
    public void setcd(int cd)
    {
        cooldown=cd;
    }
    public int getcd()
    {
        return cooldown;
    }

    public String toString()
    {
        return name+" "+specialAbility+" "+TotalHealth+" "+shieldedHealth+" "+cooldown;
    }

}

The information that follows is for Nancy’s Name Tents for the year ended December 31, 2015 and

covers questions 26-31. All per unit costs below are based on the production and sale of 3,000 name tents.

The relevant range is from 0 - 3,500 units.

Sales                                                                                                    $50 sales price per name tent                              

Costs:

Variable Costs                                                Per Tent (3,000 name tents produced and sold)     

                        Direct materials                                                          8

                        Direct labor                                                                7

Manufacturing overhead                              8

Period Costs                                                               5

            Fixed Costs

                        Manufacturing overhead                                            10                               

                        Period Costs                                                              5         

1) If 10,000 tents are produced and sold, what is the product cost per tent?

This programming assignment involves learning about some common exceptions which occur in Java programs. Consider the following exception types:

NullPointerException

ArrayIndexOutOfBounds

Exception ClassCastException

IllegalArgumentException

Research what each exception type means and the conditions under which each occurs (thrown). Then write the following programs, one for each of the above-listed exception types:

• A program which throws the exception (with a throw statement) and catches it displaying unique information about the exception. Name your programs <exception>Thrown.java

  <exception> is the name of the exception involved for example NullPointerExceptionThrown.java.

• A program which causes the exception to be thrown (not with a throw statement) and catches it displaying unique information about the exception (ex. Name of class and method causing the exception). For example, for the NullPointerException, have your program create a situation which would cause this exception to be thrown. Name your programs <exception>Catch.java <exception> is the name of the exception involved for example NullPointerExceptionCatch.java.

  At the end you should have eight programs, four <exception>Thrown.java and four <exception>Catch.java. All files should be in the same directory.

Complete the following assignment in C programming language.

1. Get the user’s first name and store it to a char array
   • Declare a character array to hold at least 20 characters.
   • Ask for the user’s first name and store the name into your char array.
   • Hint: Use %s for scanf. %s will only scan one word and cannot scan a name with spaces.
2. Get 3 exam scores from the user:
   • Declare an array of 3 integers
   • Assume the scores are out of 100, and use a for loop to get user’s input
   • Your prompts should print out which exam score you are asking for:
     1. Example: “What is the score of Exam #1?” … “What is the score of Exam #3?”
   • Warning: Be careful of your array indexes!
3. Find out the average exam score:
   • Use a for loop to calculate the sum of all exams.
   • Divide the sum by 3 to get the average and store the is data in a variable.
4. Print out the summary for the use similar to:
   • “Hello NAME, based on your exam score of 80, 90, and 100, your average is 90.0 with a letter of an ‘A.’”

(To be written in Java code)

A personal phone directory contains room for first names and phone numbers for 30 people. Assign names and phone numbers for the first 10 people. Prompt the user for a name, and if the name is found in the list, display the corresponding phone number. If the name is not found in the list, prompt the user for a phone number, and add the new name and phone number to the list.

Continue to prompt the user for names until the user enters quit. After the arrays are full (containing 30 names), do not allow the user to add new entries.

Use the following names and phone numbers:

This code was provided to start with:

import java.util.*;
class PhoneNumbers

Requirements

• using 2 classes: class Student & class Course.
• Implement the scenarios in class Test’s main method.
• Each student has a name and an id variable.
• Each object of class Student is initialized using values of name and id passed to constructor.
