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 1924 1156 1296 1444 1699

1. For each call of the method below, display the value that is returned public int retVal(int a, int b) { int c; if (a > b) { c = a; } else if (b % a == 0) { c = b; } else { c = b + (a - (b % a)); } return c; } Read the following arguments from the keyboard and pass them to retVal()Arguments passed a. retVal(4, 2) b. retVal(5, 4) c. retVal(5, 13) d. retVal(x, y) e. retVal(m, n) Output a. 4 b. 5 c. 15 d. 20 e. 8 For d and e what values are passed to produce 20 and 8?
2. Write a java program which will input an integer value from the user (Use Scanner class). Your program will have mathOper() method in addition to the main() method.The main() method will be responsible for:a. extracting the 1's digit (ones), the 10's digit (tens), and any digits larger than the 10's digit. For instance, if the input is 3562, the 1's digit would be 2, the 10's digit would be 6, and the remaining digits would be 35.b. call the mathOper() method with these 3 values,c. print the results to the screen.The mathOper() method will make the following calculations:a. Multiply the 1's digit by 7, subtract the result by 2 and then divide that by 5.b. Add 3.5 to the 10's digit, multiply the result by 4.3 and then divide that by 2.c. Subtract 5 from the remaining digits, multiply the result by 3, find the remainder after dividing that by 7, and then add 6 to the remainder value.d. Add the 3 values obtained from ‘a’, ‘b’, and ‘c’ operations.e. Return the final value.Sample output…
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.
java programming: pleas see attachment as well***** In this task, you are asked to write a program called Swap.java, including at least 3 following methods: - Main() swapDigitPairs ( parameter) - swapLetterPairs (parameter) In the main method, - Use your Panther Number as the input argument, call swapDigitPairs ( parameter) - Ask user to input a number and call a method swapDigitPairs to swap the number as shown in the example of the following figure. - Ask the user to input a string of letters/numbers and call a method swapLetterPairs to swap the letters as shown in the following example. - swapDigitPairs ( parameter) - swapLetterPairs (parameter) In the main method, - Use your Panther Number as the input argument, call swapDigitPairs ( parameter) - Ask user to input a number and call a method swapDigitPairs to swap the number as shown in the example of the following figure. - Ask the user to input a string of letters/numbers and call a method swapLetterPairs to swap the letters…
Please help me solve this with java A method named isAnOperation that takes a character and returns true if the character is one of the operations +, -, *, /, %, and false otherwise.The header of the method is as follows:public static boolean isAnOperation(char operation)2. A method named getResult that takes two floating point numbers and a character: the method returns a String that includes the two numbers, the operation, and the result. The header of the method is as follows:public static String getResult(double num1, double num2, char operation)For example, if the two floating point numbers are 12.5 and 11.4, and the operation + is passed to the method it must return the following String:12.5 + 11.4 = 23.93. In your main method:a. Read two floating point numbers from the user. You must prompt the user to enter the numbers with appropriate messages.b. Read the operation to be performed between the two numbers from the user. You must prompt the user to enter the operation with an…
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.
In Java please 6.20 LAB: Hailstone sequence (EO) Given a positive integer num, the following rules will always create a sequence that ends with 1, called the hailstone sequence: If num is even, divide it by 2 If num is odd, multiply it by 3 and add 1 (i.e. 3*num +1) Continue until num is 1 Write a method, hailstone(), that takes in a positive integer as a parameter and prints the hailstone sequence starting with that integer. Format the output so that ten integers, each separated by a tab character (\t), are printed per line. Assume the input to the program is always positive. The output format can be achieved as follows:System.out.print(num + "\t"); Ex: If the program input is: 25 the output of method hailstone() is: 25 76 38 19 58 29 88 44 22 11 34 17 52 26 13 40 20 10 5 16 8 4 2 1 Note: Your program must define the method:public int hailstone(int num) import java.util.Scanner; public class Hailstone { public static void hailstone(int num){int i =…

6. Write a method that reads three strings from the keyboard. Although the strings are in no particular order, display the string that would be second if they were arranged lexicographically. 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…
Please do this in Java! 13. isPrime Method A prime number is a number that is evenly divisible only by itself and 1. For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Demonstrate the method in a complete program. Additional requirements: Welcome the user with a message that you read from a file called "input.txt". ( inpu.txt file contains numbers between1-100.) Write the results to the terminal and also to the output file called, "output.txt" and remind the user to look at that file if he/she wants to. You only need to submit the designs, input/output files ( if applicable ) source code ( .java and not the project or the .class ) files of all the classes you'll implement and the driver program for the problem. ( Do not submit…
