JAVANotes: all program codes should be written with method/s separated from the main() structure. 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 yearsago.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.Your program must contain a method to calculate the results. Use appropriate parameters to pass information in and out of the method. Do not use any global variables.

C# (Sharp): Using visual studio a). Make a math library with 3 methods with the same name (overload): First method accepts 2 integer parameters and returns the larger number. Second method accepts 3 integer parameters and returns the larger number. Third method accepts 4 integer parameters and returns the larger number. b). Make a console application that will use and test your library methods.

T/F 5) If you call the following two methods with the same value of x, they would both return the same result. In other words, method1(x) = = method2(x).public int method1(int x){if(x > 0) return method1(x – 1) + 1;else return 0;}public int method2(int x){if(x > 0) return 1 + method2(x – 1);else return 0;}
Please help me! I have a lot of mini problems. I'm not sure how to start After #6, I have other problems. Those are : 7.) Write a method that reads a one-line sentence as input and then displays the following response: If the sentence ends with a question mark (?) and the input contains an even number of characters, display the word Yes. If the sentence ends with a question mark and the input contains an odd number of characters, display the word No. If the sentence ends with an exclamation point (!), display the word Wow. In all other cases, display the words You always say followed by the input string enclosed in quotes. Your output should all be on one line. Be sure to note that in the last case, your output must include quotation marks around the echoed input string. In all other cases, there are no quotes in the output. Your program does not have to check the input to see that the user has entered a legitimate sentence. Notes: This code requires a three-way selection statement and…
Kinetic energy is the measure of the work that an object does by virtue of its motion. It is best illustrated by the formula: KE = 0.5 mv² Create a java class that will call a method that will compute for the kinetic energy. Sample output: Enter mass of an object: 54 Enter velocity of an object: 2.87 The kinetic energy of an object is: 222.40 joules Note: 1. The result should be in 2 decimal places. 2. Apply the exception handling method. 3. SCREENSHOTS NOT ALLOWED! 4. Save your file as KineticPT.java.
