- 8.3.2: HashMap with enhanced for loop. Declare variable scoreToGrade as a HashMap with Character key type and Double value type, representing a grade and the minimum score of the grade. Read integer numToRead from input. Then read numToRead key-value pairs from input and insert each into scoreToGrade. If the key already exists, replace the key's existing value with the new value. Ex: If the input is: 3 D 60.0 A 89.0 A 90.5 then one possible output is: Key: D, Value: 60.0 Key: A, Value: 90.5 Note: The order of the keys is not guaranteed in a HashMap. import java.util.Scanner;import java.util.HashMap; public class GradeScale {public static void main(String[] args) {Scanner scnr = new Scanner(System.in);char assignedGrade;double minScore;int numToRead;int i;/* Any variable declarations go here */ /* Your code goes here */ // For each key in the HashMap, retrieve the value associated with the keyfor (Character key : scoreToGrade.keySet()) {System.out.println("Key: " + key + ",…#2.

- Part 1: Write the implementation of class called Point, that represent any point with x and y coordinates. Provide a parametrized default constructor to set the attributes x and y according to the values specified in the parameter list, or to the default value 0. Provide setters and getters functions for the attributes x and y. Overload the stream extraction operator for easy input of x and y values Overload the stream insertion operator for easy output of x and y values. Overload equality operator (==) as member function to check whether two points have the same coordinates or not.5.9 LAB - Database programming with Java (SQLite) Complete the Java program to create a Horse table, insert one row, and display the row. The main program calls four methods: createConnection() creates a connection to the database. createTable() creates the Horse table. insertHorse() inserts one row into Horse. selectAllHorses() outputs all Horse rows. Complete all four methods. Method parameters are described in the template. Do not modify the main program. The Horse table should have five columns, with the following names, data types, constraints, and values: Name Data type Constraints Value Id integer primary key, not null 1 Name text 'Babe' Breed text 'Quarter horse' Height double 15.3 BirthDate text '2015-02-10' The program output should be: All horses: (1, 'Babe', 'Quarter Horse', 15.3, '2015-02-10') This lab uses the SQLite database rather than MySQL.

Using the BasketballTeam class above, write a complete demo driver class on the next page, which simulates a basketball game in the following way: instantiate two teams as above, and then assume the teams alternate possession of the ball for 20 times each. During each possession (show each possession of the ball with an if-else chain), the team with the ball has the following probabilities: 35% chance of making a 2-point shöt 15% chance of making a 3-point shot 20% chance of making a free throw 30% chance of turning over the ball without scoring Use a double variable set to equal Math random(), together with some if-else statements, to control the probabilities. After each possession, print the score of both teams to the screen.
