- JAVA Notes: 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 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. Your program must contain a method to calculate the results. Use…1. Write a Java program that will ask for a string of letters . 2. Each letter in the alphabet is given the following number code as assignment . 3. Print out the number code of each letter from the input in reverse . 4. Ask if the operation should be done again, if Yes, Return to 1. if No. Terminate the program 5. Create at least 2 methods aside from your main method in implementing a solution for this problem.Correct the following wrong statements. In Java, once a variable is declared in a method as local variable, it will be visible and could be used in any other method in the program.
- 4. Write a java method to calculate the area of the square(the method should take one parameter and doesn't return a value.Program62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below) Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square.1. Write a Java program that will ask the a user a number between 1 to 7. 2. Print out the equivalent day of the week for that number. Starting 1 for Sunday, 2 for Monday and etc. 3. Use at least 1 user-defined method aside from your main method in writing a code for this problem
- True or False A Java method can be defined to accept a varying number of parameters.Writing Methods that Return a Value in Java In this lab, you complete a partially written Java program that includes a method that returns a value. The program is a simple calculator that prompts the user for two numbers and an operator ( +, −, *, /,or% ). The two numbers and the operator are passed to the method where the appropriate arithmetic operation is performed. The result is then returned to the main() method where the arithmetic operation and result are displayed. For example, if the user enters 3, 4, and *, the following is displayed: 3.00 * 4.00 = 12.00 The source code file provided for this lab includes the necessary variable declarations, and input and output statements. Comments are included in the file to help you write the remainder of the program. Instructions Write the Java statements as indicated by the comments.

In Java, once a variable is declared in a method as local variable, it will be visible and couldbe used in any other method in the program.3. All binary operators except for the assignment operators are evaluated as user intention.4. In Java, byte code is translated to native code by java compiler.5. Each row in a single dimensional array could be dealt with as 2-dimensional array.6. The indices of elements in a single dimensional array named arrElem are from 1 toarrElements[]length.7. In Java, method overloading means that a program may contain more than one methodwith same signatures. Each column in a 2D array could be dealt with as 1D array.8. The following statement creates and initializes the 2-dimensional array values:short values[][] = {10, 20, 30, 40, 50};9. A ragged 2D array is a 2D array in which each row may contain the same number ofcolumns.10.…
