- write code in java write a static method that will take in a lone integer parameter. this function will return 1 if the number provided is odd, 0 if it is even. write a line of code that will call the function you just wrote above, passing it the contents of a variable called value and have it assigned the value returned by the function another variable called answer(both variables are already declared.)1- Write a java program as follows: a- Write a method called isEven that takes an integer as parameter. The method should return true if the integer is even or false otherwise. b- Write a method called powOfTwo that takes an integer as parameter, computes, and outputs it's square (power of 2). c- In the main method, write a program that invokes the previously created methods to display the power of 2 of all the even numbers between 1 and a maximum number entered by the user. Your program should print a maximum of 5 results per line as shown in the below sample run. Sample run: Enter a number 50 4 16 36 64 100 144 196 256 324 400 484 576 676 784 900 1024 1156 1296 1444 1600 1764 1936 2116 2304 2500Writing Methods that Require a Single Parameter in Java In this lab, you complete a partially written Java program that includes two methods that require a single parameter. The program continuously prompts the user for an integer until the user enters 0. The program then passes the value to a method that computes the sum of all the whole numbers from 1 up to and including the entered number. Next, the program passes the value to another method that computes the product of all the whole numbers up to and including the entered number. The source code file provided for this lab includes the necessary variable declarations and the input statement. Comments are included in the file to help you write the remainder of the program. Instructions Ensure the file named SumAndProduct.java is open. Write the Java statements as indicated by the comments. Execute the program by clicking "Run Code." USE THE GIVEN CODE // SumAndProduct.java - This program computes sums and products. //…
- Method Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.Language:Java - Requests two double values from the user and stores them in local variables in main() - Create a method which takes these two values as parameters- The method will use Math library functions to: o Print the square root of the 1st parametero Print the log of the 2nd parametero Print the value of the 1st parameter raised to the power of the 2nd parameterJAVA 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…
- Define a method in JAVA that should take 4 numbers as the parameters and returns the average of all the numbers. The function return type should not be void i.e. the average value should be returned by the function.Ql: Write a java program that includes a method called Reader that reads unlimited number from the users, then you have to determines the following: a. How many even values b. How many odd values c. Computes the total of the input values d. Computes the average of the of the input values e. The program should be ends with the input 0 (not counting zero as an input).The method half shown below, takes a variable of type int and returns the result of dividing the variable by 2. Write the overloaded method for half that accomplishes the same task for a variable of type double. public static int half(int val) { return val/2;}
- Write a Java program that will call a method (called f) to tabulate the following function. f(x) = x2 - 16Using 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.ISP- Java A pedometer treats walking 2,000 steps as walking 1 mile. Write a program whose input is the number of steps, and whose output is the miles walked. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("%.2f", yourValue); Your program must define and call a method: public static double stepsToMiles(int userSteps) Ex: Ex: If the input is: 8790 the output is: 4.40
