Java

BasketBall Bar Chart Write a program that allows you to create a bar chart for the active members of a basketball team during a game. (Recall: there are only 5 active players on the court per team in a standard basketball game.) Your program should do the following tasks: 1) Prompt the user to store the first name of the five players 2) Prompt the user to enter the points scored by each player a. Use a do...while loop to check for input validation for the points (which cannot be negative) 3) Calls a method to construct the chart for each player (based on the number of points). The method should have the following characteristics: a. The method accepts two parameters - the player name and the points scored by that player b. The method does not return a value C. The method generates an asterisk (i.e. *) for every point scored. For instance, it should display *** if the player scored 3 points. Use a for loop to generate the asterisks. d. Use the format method from the String class to align your player's names neatly. (See the following pages to learn how this is done!) A sample of the output is shown below: Enter the first names of the 5 players: Jaden Tommy Danny Mason Bobby Enter points earned by Jaden: 12 Enter points earned by Tommy: 6 Enter points earned by Danny: 4 Enter points earned by Mason: 1 Enter points earned by Bobby: 9 Points for Game Jaden Tommy Danny Mason Bobby

Here I am sending code, screens of code and outputs. Refer the screens for better understanding. if any queries comment below. Thank you.

Code:

import java.util.*;
public class BarChart
{
   static void chart(String name,int points)
   {
       String star= "";//empty string.
       for(int i=0;i<points;i++)//adding points number of stars.
           star=star+"*";
       String s = String.format("%s\t%s",name,star);//printing name and stars.
       System.out.print(s+"\n");
   }
   public static void main(String args[])
   {
       Scanner sc = new Scanner(System.in);
       String names[] = new String[5];
       int points[] = new int[5];
       System.out.print("Enter the first names of the 5 players: ");
       for(int i=0;i<5;i++)//reading first names of 5 players.
           names[i] = sc.next();
       int i=0;
       do
       {
           System.out.print("Enter pointer earned by "+names[i]+": ");//reading the points of each player.
           points[i] = sc.nextInt();
           if(points[i] < 0)//if entered points is negative
           {
               while(true)//asking the user again and again till enter correct points.
               {
                   System.out.print("Invalid points. Please enter correct points of "+names[i]+": ");//reading points
                   points[i] = sc.nextInt();
                   if(points[i] >= 0)//entered correct points then stop the infinity loop.
                       break;
               }  
           }
           i++;
       }while(i<5);//condition
       System.out.print("\nPoints for Game\n\n");
       for(i=0;i<5;i++)
       {
           chart(names[i],points[i]);//passing the name and points of each player.
