- Using the Java programming language write a program that takes an email address as an input from the keyboard and, using a loop, steps through every character looking for an @ sign. If the email address has exactly one @ character, then print a message that the email address is valid; otherwise, print a message that it is invalid.Write a program that gives simple math quizzes. The program should display two randomnumbers that are to be added, such as:247+ 129The program should allow the student to enter the answer. If the answer is correct, a message of congratulations should be displayed. If the answer is incorrect, a message showing the correct answer should be displayed.In JavaScript, write a program based on the following pseudocode: given a variable "y" set to 0for each number from 0 to 12:if the number is even, thenincrement "y" by 5otherwisedecrement "y" by 4
- In Java code Write a program that takes in an integer in the range 11-100 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical.Write a program that uses a random number generator to generate a two digit positive integer and allows the user to perform one or more of the following operations: Double the number. Reverse the digits of the number. Raise the number to the power of 2, 3, or 4. Sum the digits of the number. If the number is a two digit number, then raise the first digit to the power of the second digit. If the number is a three digit number and the last digit is less than or equal to 4, then raise the first two digits to the power of the last digit. After performing an operation if the number is less than 10, add 10 to the number. Also, after each operation determine if the number is prime. Each successive operation should be performed on the number generated by the last operation. Your program should not contain any global variables and each of these operations must be implemented by a separate function. Also, your program should be menu driven.Write a program that uses a random number generator to generate a two digit positive integer and allows the user to perform one or more of the following operations: Double the number.

When the user types an even number, display the message “Good job!” and then ask for another input. When the user types an odd number, display an error message, "x is not an even number", and then ask for another input. When the user types the sentinel value 999, end the program. The EvenEntryLoop program displays the proper message for each input.

The program should display two random numbers that are to be added, such as: 247 + 129 The program should allow the student to enter the answer. The program should then display whether their answer was right or wrong, and accumulate the right values. After the 10 questions are asked, calculate the average that was correct. Then display the student name, the number correct, and the average correct in both decimal and percentage format. In addition to any system functions you may use, you might consider the following functions: A function that allows the student to enter their name. A function that gets two random numbers, anywhere from 1 to 500. A function that displays the equation and asks the user to enter their answer. A function that checks to see if the answer is correct and accumulates the number correct. A function that calculates the…Using Java (InputMismatchException) Write a program that prompts the user to readtwo integers and displays their sum.
