Question

Part A

Java netbeans

☑ Create a project and in it a class with a main.

We will be using the Scanner class to read from the user. At the top of your main class , after the package statement, paste

import java.util.Scanner;

As the first line inside your main method, paste

Scanner scan = new Scanner(System.in);

Remember when you are getting a value from the user, first print a request, then use the Scanner to read the right type from the user and put it in a variable of that type.

In the main, do the following:

(You can use if, if-else, nesting, or boolean operators. You may not use special math methods, just relational and algebraic operators.)

☑ Get an int n from the user and print "high" "middle" or "low" depending on whether n is above 75, between 25 and 75, or below 25, but if it is exactly 75 or 25 print "hard to say"

☑ Ask the user their favorite animal and get a String as their answer. For five possible values ("cat" "dog" "capybara" etc... your choice) if the user said that animal, print a specialized comment about it (e.g. if they said "cat" you might print "oh, purr!"). If they said none of the types your program covers, instead print a general comment for all other types of animal.

☑ At a certain amusement park, children under 5 get in for $4, children up to (inclusive) 12 get in for $10, teens up to 19 get in for $12, adults up to 59 for $15, seniors up to 79 for $10, and seniors 80 and over for $5. In your main, ask the user for their age. Create a a single compound if-else statement that goes through all the possibilities for admission price above and prints out the appropriate price, given the user's age.

☑ [EC+10] read in an x from the user and print "even" if x is even and "odd" otherwise. You do not need any special math methods to do this.

//create class NestedIF.java and paste the code given below

*whether n is above 75, between 25 and 75, or below 25,
