Question

Write a program that lets the user enter the name of a team and then displays the number of times that team has won the World Series. The WorldSeriesWinners.txt file contains a chronological list of the world series winning the World Series in the time period from 1903 to 2018. Tips and tricks: Question. How do I use arrays to complete this assignment? Answer 1: You can use arrays if you want. You will need read the file twice, first time to determine the number of lines in the file, and then the second time to assign values to the elements of your array. You will have to create this string array with the size that you found out by reading the file the first time. Answer 2. Do not use arrays, use ArrayList class instead. The topic is covered in Chapter 7 of your text book. We will cover the material during the next lecture, but there is nothing that prevents you from using this class.

Answer 1

Answer:

see explaination

Explanation:

import java.io.*;

import java.util.Scanner;

public class Winners {

public static void main(String args[]) throws IOException {

Scanner sc = new Scanner(new File("WorldSeriesWinners.txt"));

String commands[] = new String[100000];

int c = 0;

while (sc.hasNextLine()) {

String input = sc.nextLine();

System.out.println(input);

if (input.isEmpty())

continue;

commands[c++] = input;

}

sc.close();

Scanner keyboard = new Scanner(System.in);

System.out.println("Enter the name of a team: ");

String name = keyboard.nextLine();

int count = 0;

for (int i = 0; i < c; i++) {

if (commands[i] != null) {

if (commands[i].equals(name)) {

++count;

}

}

}

if(count!=0)

System.out.println(name + " has won the World Series in the time period from 1903 through 2018 " +count + " number of times" );

else

System.out.println("Team with name "+name+ " does not exists");

}

}
