Write the appropriate method headings using the provided method name for the following processes:
1.) Given the radius of a circle, print the area of a circle - printArea.Â
2.) Accept an integer, compute for the square of the number and return the String equivalent of the square of the number - makeStringÂ
3.) Calculate and return the sum of two decimal numbers - getSum.
4.) Given a student’s name and three test scores (of type int), print the student’s name and average test score - printStudentDetails.Â
5) Compute and return the average speed of a car, given the distance traveled (as type double) and traveling time (in hours and minutes, both of type int) - getAverageSpeed.

Part 4: Methods
The following is Java pseudocode. For this exercise, you can assume the input function provides an appropriate integer value. Line numbers are provided on the left. System.out.print will print the information to the same line. System.out.println will print the information and then go to the next line. // is a comment. Do not worry about public static. Code execution starts with the main method.
For each method used, make sure to provide a separate table showing what the values are and how they change (i.e. tracing through the code). All variables passed in have values. Don’t worry about showing how the input() method works.

Use a separate code files for each. Programming Problems: 1. Write a value-returning method, isVowel, that returns the value true if a given character is a vowel, otherwise return false. Also write a program to test your method. 2. Write a program that prompts the user to enter a sequence of characters and output the number of vowels and consonants separately. (use the method isVowel written in problem 1). 3. Write a program that output inflation rates for two successive years and whether the inflation rates are increasing or decreasing. Ask the user to input the current price of an item and its price, one year and two years ago. To calculate the inflation rate for a year, subtract the price of the item for that year and from the price of the item from one year ago and then divide the result by the price a year ago.

- Write a Java program to sell a limited number of cinema tickets. Each person can buy up to 4 tickets, where the number of available tickets is 100. Your program should do the following: 1. Prompt the user for the number of tickets to buy. 2. Display the number of remaining tickets. 3. Repeat the above steps until all tickets have been sold. Display the total number of buyers. 4. Invalid testing: (1) If the number of tickets to buy is negative or zero, then print an invalid message. (2) If the number of tickets to buy is more than 4, then print a message that the maximum tickets to buy is 4. (3) If the number of tickets to buy is more than the available tickets, then print a message that there are no enough tickets available.
