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:

• Prompt the user to store the first name of the five players

• Prompt the user to enter the points scored by each player

a. Use a while or do…while loop to check for input validation for the points (which cannot be negative)

• 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 Week 3 Lecture 1 Class code for a recap of this concept.)

A sample of the output is shown below (note: the text does not have to be exact. This output included to show you how the ‘chart’ would be generated):

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 *********

Answer 1

All the explanations is given in the comments of the code itself.

Code--

import java.util.*;
public class Program
{
   //method to print the chart
   public static void constructChart(String []name,int[] points)
   {
       int i,j;
       for(i=0;i<5;i++)
       {
           //allign the string properly while printing
           String temp="";
           for(j=1;j<=points[i];j++)
           {
               temp=temp+"*";
           }
           temp=String.format("%s\t%s",name[i],temp);
           System.out.println(temp);
       }
   }
   //main method
   public static void main(String[] args)
   {
       Scanner sc=new Scanner(System.in);
       String[] name=new String[5];
       int[] points=new int[5];
       int i;
       //prompt the user to store the names
       System.out.println("Enter the first names of the 5 players:");
       for(i=0;i<5;i++)
       {
           name[i]=sc.nextLine();
       }
       //validate the input using do while loop
       //and get input for the scores
       i=0;
       do
       {
           System.out.print("Enter points earned by "+name[i]+": ");
           points[i]=sc.nextInt();
           if(points[i]>=0)
           {
               i++;
           }
       }while(i<5);
       System.out.println("Points for game:");
       //call the method
       constructChart(name,points);
   }
}
