University of Washington Main Method Skeleton Drive Project
Given the following variable declarations and main() method skeleton driver below, code up “if” statements that correspond with each of the questions below. (A driver is a program whose purpose is to run other code, in this case, the "if" statements.) Compile and execute your code to prove it’s correct. Use a Scanner to initialize each data item.
Prompt the user with: "Enter the number". Determine if it is negative and if so, print: "The number is negative." Use a Scanner to collect the input, and report to the console if the variable called “number” is negative using System.out.println().
Prompt the user with: "Enter a second number". Determine if the number is zero and if so, print: "The number is zero." Use a Scanner to get the input, and report if the number is zero next. You can reuse the variables "number" and "keyboard" here.
Continue to use Scanner for input. Prompt the user with: "Enter a third number, a double, for the class average." Determine if the class average is a passing grade, and if so, print: "A passing grade", and print to the console otherwise if not (not passing is if the class average was below a 65).
Prompt the user with: "Is the answer the user reported true? Enter a Boolean value." Store the value in the variable called "answer". Let the user know if the value in the variable “answer” is true by printing an appropriate message to the console.
Starting with the "if" statement you built in the previous problem, add an "else" clause to it so that if the answer was false, your program will output "The value was false" instead.
Ask the user for a number and then determine if the number is even or odd. Print out “the number is even” if the “number” variable holds an even value, else { print out “the number is odd” }
Ask the user for a float value (i.e. real number, data type = float) that will represent a grade and determine if the grade is in the “A” range. Print to the console “The grade is above an X” (where X is the minimum value for an "A" grade) if the grade is an “A”. (See the grading tables linked in the Syllabus for the value.)
Add to the previous "if" statement so that it becomes an "if/else" structure that will now also test to see if the grade is a “B”? Output to the console if the grade is in that range. (Note the use of “&&” for logical "and" in Java.)
Ask the user for a temperature, stored in a double. Is the temperature higher than 78 degrees or less than (or equal to) 78 degrees? Describe the current temperature as “higher than 78 degrees” or “less than or equal to 78 degrees”.
For the temperature, write an "if/else" statement that asks if the temperature is (positive AND odd) OR (zero AND even)? (Notice the use of parenthesis here to define operator precedence. Look up order of operations (PEMDAS) and “logical AND” if this is unfamiliar in your text). If it is, output “yes; positive and odd, or zero and even.” and if it’s not, say “no; not positive and odd” on the console.
Prompt the user for a letter grade and store this in a char. Then, write a multi-way "if" statement that ends in a catch-all if a non-existent letter grade (i.e., not A, B, C, D, F) is entered. The multi-way "if" asks: Is the grade an “A”? Else is the grade a “B”? Else is the grade a “C”? Else is the grade a “D”? Else is the grade an “F”? For each case, print an appropriate message to screen as to what letter grade was entered (or if a non-existent grade was entered). Notice the use of the word else in the sentence above, which provides for a more precise meaning. In spoken English we might use the word “or” instead, but of course, English is terribly ambiguous and Java needs to be discrete, deterministic, and precise.
Write a method called “max” that takes two integers as input and returns the larger of the two. That is, complete the function “public static int max(int a, int b) {“ so that it returns the larger of a or b using an “if” statement (hint: lab #2 has a similar question, using Math methods. Your job is to build a method that will perform the same functionality as Math.max)
Ask the user for two integers using a Scanner and report the largest and smallest values using the max method you just built. Consider the following output:
//sample output for problem 13
Enter two integers: 2 14
Largest is 14
Smallest is 2
Main Method Skeleton Driver
//Driver for if statement warm-up
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
//TODO 1
System.out.println("Enter the number for TODO 1");
int number = keyboard.nextInt();
if( the number is negative ) { //you must fix this pseudocode before you can compile it
System.out.println("The number is negative");
//TODO 2
number = ?;
//TODO 3
double average = ?;
//TODO 4 & TODO 5
boolean answer = ?;
//TODO 6
number = ?;
//TODO 7
float grade = ?;
//TODO 8
grade = ?;
//TODO 9
double temperature = ?;
//TODO 10
number = ?;
//TODO 11
char letterGrade = ?;
//TODO 12: See below for the max function/method
//TODO 13
}
public static int max(int a, int b) {
//TODO 12
}
Notes and Hints
Always compile and run/test your code after each incremental change.
Never write a whole program first and then compile and test later.
Grading
Each item is worth 2 points. For this assignment, points are awarded strictly based on whether your program is correctly written to produce the correct results. You will not be graded on style, though you should always practice good programming style.

Rasmussen College Java Software Development Project
You are working as the software developer and need to solve the problem using the inheritance concept. Your goal is to create the method to sort the numbers and then perform the addition. Here are the steps that need to be completed.Step 1: Create the base class that has the sorting method. The sorting method should take the input parameter as the array and print the sorted array.Step 2: Create the child class that inherits all the methods from the above base class. The child class has the addnumber method that adds all the numbers from an array. The addnumber method first calls the base class sorting method to sort all the array numbers. Once the numbers in the array are sorted, then addnumber method adds all of them.Your submission should include the following:Base ClassChild ClassEntire Java SolutionOutput screenshot created in Microsoft Word
