In java Write a program on value passing from one method to another and also write separate program for 1. Value passing from one class to another 2. Multiple value passing from one method to another

3. Write a java program as in the next class diagram, such as: SimpleCalc2 SimpleCalc2() method only calls find method. find() method: asks the user to enter two numbers and a math operation like(+,-,*,/) and prints the result like (inputs and outputs only) - X: double + y: double + getX(): double Enter no1: 4 Enter no1: 5 Enter no1: 5 + setX(double x): void Enter no2: 7 Enter no2: 7 Enter no2: 7 + SimpleCalc20 Enter operation: * Enter operation: + Enter operation: - + find() : void 4*7=わ28 5+たす7=わ12 4-ひく9=わ-ひく5 + advanced(String s): void advanced(..)Let the user enter a whole line like (5+8) and analyse it, then prints result

Java requires its method arguments to be sent in as values, not references. And what, precisely, does it entail?

basic java please Write a method called findTip that finds the value of a meal as a double after adding the tip to the cost. Then return this value to the calling function. For example findTip(120.10, 5) would 126.105 because that is a 5% tip. While findTip(48.0, 15) would return 55.2 because that is a 15% tip. Note that the bill is a double while the tip is an int. Don’t worry about rounding to two decimal places, just return the full value as a double.

please quickly thanks ! use java

JAVA METHOD OVERLOADING

in java

Write a code in Java programming You are working in a game company that is developing a new RPG game. One of the core features of the game is the ability to create and manage different types of characters, such as warriors, mages, and archers. However, your colleague, who was previously working on the implementation of the CharacterManager class, has been laid off due to excessive absences. You have been assigned to take over the project and complete the implementation of the class based on the design specifications outlined below: Given the following main method: public static void main(String[] args) { CharacterManager manager = CharacterManager.getInstance(); manager.createCharacter(CharacterType.WARRIOR).attack(); manager.createCharacter(CharacterType.MAGE).attack(); manager.createCharacter(CharacterType.ARCHER).attack(); } Your output should be: Warrior is attacking Mage is attacking Archer is attacking Note that you should not change the method signature.

public class process{ static int result; public static int addition(int a, int b) { result = a + b; return result; } public static int subtraction(int a, int b) { result = a-b; return result; } public static int multiplication(int a, int b) { result = a*b; return result; } public static void main(String[] args) { System.out.print("Enter First Number :"); Scanner s = new Scanner(System.in); int a = s.nextint(); System.out.print("Enter Second Number:"); Scanner p = new Scanner(System.in); int b = p.nextint(); addition(a,b); System.out.printin("First Number :" +a); System.out.println("Second Number :" +b); System.out.printin("Addition Result :" +result): substruction(a,b); System.out .printin("Subtraction Result:" +result); multiplaction(a,b); System.out.printin("Multiplication Result "+result); !3! What does the above program do? Explain it.
