Write a program using java programing language. Write a Java class (called ShowNum) that displays the same number of asterisks (row and columns) as is input in 2 numbers.  Your class should have a default constructor (number1 is 0, number2 is 0) and  another constructor that inputs 2 numbers (integers).  You'll need accessor methods for the numbers and a display method that displays as follows:  Input:   2, 7      ******* ******* Demo the class in a client (called ShowNumClient) that allows the user to run the program as many times as they want (enter number and use display method).  The user will signal with a sentinel (-1), when they want to terminate the client.  Make sure that each number entered in the client is between 1 and 30.

Hello, I have written my random bear generator but for some reason the code isn't running in my command terminal. Please have a look at it and let me know what I am missing. I followed my teachers instructors and lectures, but it doesn't run on another compiler either. class Bear {  constructor(type, color, weight, favoriteFood) {    this.type = type;    this.color = color;    this.weight = weight;    this.favoriteFood = favoriteFood;    if (this.weight === 700 || this.type === "Little Bear" || this.type === "Baby Bear") {      this.isAggressive = false;    } else if (this.weight === 1200 || this.type === "Papa Bear" || this.type === "Black Bear") {      this.isAggressive = true;    } else {      this.isAggressive = Math.random() < 0.5;    }    if (this.type === "Winnie the Pooh Bear" && this.favoriteFood !== "Honey") {      throw new Error("Winnie the Pooh Bear must have Honey as his favorite food.");    }  }} class BearGenerator {  get types() {    return [      "Winnie…

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.
