- 4. Get user to enter a phrase and print out how long the phrase is(Hint: use String method). Expected output: ----jGRASP exec: java LabActivity10_4 Enter a phrase I am Beyonce always Your phrase length is 19 ----jGRASP: operation complete 5. Create a void method called greet that prints "Hello". Call the greet method in your main method. (Remember, void is just a substitute for the datatype of your method when you don't return a value) ----jGRASP exec: java LabActivity10_5 Hello ----jGRASP: operation complete.Java Your program will read in a credit card number and expiration date from the user and validate the data. The program will continue to ask for user input until a valid number and date are entered. The rules for what is valid are specified below. readYear() and readMonth(int) methods Complete the readYear() and readMonth(int) methods. These methods ask the user to input the expiration year and month of their credit card. Each method should contain a loop inside the method so the code repeats until a valid month or year is entered by the user. If the user enters an invalid year or month, print an error message and ask them to try again. The readMonth(int) method reads in the month as a number. A valid month is any number between 1 and 12 (inclusive). A valid year is 2022 or later. readCreditCardNumber() method Complete the readCreditCardNumber() method. This method asks the user to input their credit card number. This method should contain a loop so the code repeats until a valid…Use Java programming language Write a program that asks the user to enter 5 test grades (use an array to store them). Output the grades entered, the lowest and highest grade, the average grade, how many grades are above the average and how many are below and the letter grade for the average grade. Create a method that returns the lowest grade. Create a method that returns the highest grade. Create a method that returns the average grade. Create a method that returns how many grades were above the average. Create a method that returns how many grades were below the average. Create a method that returns the letter grade of the average (90-100 - A, 80-89 - B, 70-79 - C, < 70 - F)

The numbers are given by user. Input : 17 -6 Output: The greatest number is 17 2.Use a class and add a method called greatestNumber1. a). Write a method called generate() that will generate and return an eight digits integer random number. b). Write a method called check() that is passed with eight digits integer random number as an argument to check and return true if the given random number is multiples of 4, otherwise return false. c). Write a main() method to call and execute the generate() method for 10 times and then pass this eight digits integer number to check() method for 10 times and display the result. Page 1 2. What is the value of x and y after executing the following program? public class MysteryNums { public static void main(String] args) { int x = 15; sentence(x, 4); int y = x - 5; sentence(y , x ); System.out.printin(x + " & " + y); } public static void sentence(int num1, int num2) { num1 = num1 + num2; } }
- The formula to calculate the Icm value is value of Icm = (number1 * number2) / value of gcd e). Write a main() method to call and execute the randomMethod() method for 2 times to get the two integer numbers and then pass these two integer numbers to Icm() method to get the Icm value. 4. Write a Java program named RandomNumber that generates 10 integer random numbers (their range must be between 1 and 100 inclusive) and stores them in an array. The program should find and display how many numbers are between 25 and 75 inclusive. For example, if the random numbers are: 35 36 47 4 19 38 83 15 46 47 Then the program should display: There are 6 numbers between 25 and 75 5. Write a Java program named Grade that asks the user to enter 5 marks of a student and store them in an array. Then it should compute and display the average mark. Then it should find and display the highest mark. Sample run of the program: Enter 5 marks (a mark is between 0 and 100): 85 40 69 39 70 The average mark is:…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.

- Using Java, Write a method named isEven that accepts an int argument. The method should return true if the argument is even, or false otherwise. Also write a program to test your method.Write a program that contains 2 methods, main and printLine 1) The printLine method will do the following:a. receives 3 parameters: the first character, the second character and thenumber of times to print the characters.b. using a loop, the program prints a line of text consisting of the first characterconcatenated with the second character repeated the number of timesentered by the user. 2) The main method will do the following:a. asks the user for a character.b. using a Scanner gets the characterc. asks the user for a second character.d. using a Scanner gets the second charactere. asks the user how many times to printf. using a Scanner gets the number of times to printg. calls the method printLine. Sample Run:Enter a character?Enter a second character*Enter the number of times to repeat5?*?*?*?*?*Enter a character!Enter a second character@Enter the number of times to repeat8!@!@!@!@!@!@!@!@ Submission• Copy and paste your code• Screen shot the console with ANY TWO Sample RunHint:…Write a program that asks the user to enter a character. Then pass the character to the following methods. a) isVowel() – returns true if the character is a vowel b) isConsonant() – returns true if the character is a consonant Example output is given below: Enter a character a a is a vowel a is not a consonant You can use the following code to read a character from console. When you call charAt(i) method for any String it returns the character at index i. The index of first character is 0, the index of second character is 1 and so on. Scanner input = new Scanner(System.in); char ch =input.next().charAt(0); If you cannot pass the tests, please try following for troubleshooting: isVowel('e'); # should be True isVowel('d'); # should be False isConsonant('e'); # should be False isConsonant('d'); # should be True class Main {// Add your code belowpublic static void main(String[] args) {}public static boolean isVowel(char c) {}}
