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.
PS: Please upload the output and say the logic behind it. Thank you! 2. Create a class with a method. The method has to decide whether a given year is a leap year ornot.a. Note: A year is considered a leap year if:i. It has an extra day i.e. 366 instead of 365.ii. It occurs every 4 years e.g. 2008, 2012 are leap years.iii. For every 100 years, a special rule applies - 1900 is not a leap year but 2000 is aleap year. In those cases, we need to check whether it is divisible by 400 or not.
Java RMI modify “MyClient.java”, “Method.java” and “MethodRemote.java” After your modification, re-compile, and run server and client programs, the client asks the user to enter a string. • If a string “time” is entered, the client will get current date and time from server by remotely invocating the method “action()” in server machine. • If another string other than “time” is entered, then the client will get the capitalized version of the string the user just entered by remotely invocating the method “action()” in server machine. • Your client program should keep asking the user’s input for a string unless an empty string is entered (i.e., just press ENTER key without anything else). When an empty string is entered, this client will quit. while a client is being connected to the server, the server should be able to receive new clients’ connections for current date/time or capitalized strings. In other words, the server should concurrently handle multiple clients’ connections and…
Write a java program that models a restaurant ordering system. You will need to have the following methods: public static int displayMenu() This method will display the menu items and price per item. Please keep the same 5 items as I have. You need an option so that the customer can indicate that ordering is done. This method will read the choice from the customer and return that number. public static double getQuantityAndCost(int x) This method will prompt the user for the quantity for the menu choice and then multiply by the appropriate amount. For example, if the user had selected Tacos, then x would be passed in as the value 2 and the return value for this method would be 2 * 4.00. public static double AddTipAmount(double sum) This method will prompt the user for a tip amount. The method receives sum which is the total on the bill after the user has selected Done ordering. For example, the method is called with a sum of 22.00 and the user indicate 10 percent for the tip, the…
*in java* Write a method printShampooInstructions(), with int parameter numCycles, and void return type. If numCycles is less than 1, print "Too few.". If more than 4, print "Too many.". Else, print "N: Lather and rinse." numCycles times, where N is the cycle number, followed by "Done.". End with a newline. Example output with input 2: 1: Lather and rinse. 2: Lather and rinse. Done. Hint: Declare and use a loop variable. import java.util.Scanner; public class ShampooMethod { /* Your solution goes here */ public static void main (String [] args) {Scanner scnr = new Scanner(System.in);int userCycles; userCycles = scnr.nextInt();printShampooInstructions(userCycles);}}
Write a java program which asks the user to enter name and age and calls the following methods: a. printName(): Takes name as parameter and prints it 20 times using a while loop. b. printAge(): Takes age as parameter and prints all the numbers from 1 up to age. Please strictly follow this format. Note: any extra or missing space / line will lead to test failure. Name: Andy Age: 10 Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy 1,2,3,4,5,6,7,8,9,10 class Main {public static void main(String[] args) {}}
Write a java program that converts LBP amount to USD The program stops when the user inserts 0 Your program must contain a method called "IbpTousd" that converts an LBP amount to USD. lbp Tousd method takes two doubles as parameters, LBPamount and USDrate and returns the actual amount. The program prompts the user to enter the USD rate at first. Your should execute exactly as the below sample run. program PS: Using IbpTousd method is a must. Sample Run: Enter USD Rate for Ioday: 12000 Enter LBP Amount: 1200000 400.09 Enter LB2 Amount: 600000 50.05 Enter LBP Amount: 0000 66,666666666666675 Enter LB2 Amount:0
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.
Write a java program method that accepts a year as a parameter, the method then returns true or false if the entered year is a leap year or not. You may calculate the leap year as follows: 1. If the year is evenly divisible by 4, go to step 2. Otherwise go to step 5. 2. If the year is evenly divisible by 100, go to step 3. Otherwise go to step 4. 3. If the year is evenly divisible by 400, go to step 4. Otherwise go to step 5. 4. The year is a leap year (it has 366 days). 5. The year is not a leap year (it has 366 days).
Create a calculator program. Get 2 numbers from the user. Create a method that adds the 2 numbers. Create a method that subtracts 1 number from the other. Create a method that multiplies the 2 numbers. Create a method that divides one number by another. It is important to check that you are not dividing by 0 here. You should be calling these methods from the main method and printing out the answers from the main method. Create a method that uses the modulus to return the remainder and the language is Java
Write java method fullName with a return type of void and accept a name. The method will display the abbreviation of the firstname and middle name except for the lastname. For example, if name is Yule Plaza Sanchez it will display: Y.P.Sanchez For example: Test Result fullName("Yule Plaza Sanchez"); Y.P.Sanchez fullName("Yule Josef Plaza Sanchez"); Y.J.P.Sanchez
We invoke, or call, another method when we want to execute it. The invoked code is not defined in the program we write, rather it is part of the System object which is part of the Java standard class library. Hence, we can call it. Example: println method. True or false
