Homework SourseTo begin download the text file and save it in the same fold
To begin, download the text file and save it in the same folder as your java source files: http://courses.cs.tamu.edu/hurley/cpsc111/homework/SuperBowlWinners.txt Next, write a program that opens and reads the data from this file into a 2D array. Each row of your array corresponds to one line of the file. The first column should contain the year and the second column the full team name. Then ask the user to enter a year, and output the team that won the SuperBowl that year. Give an error if the year is not in the data. Let the user keep entering a year until they enter STOP. Hint: Remember that Scanner gives you different options for reading input. For example, the next() method stops reading when it sees a space, tab, or newline character, while the nextLine() method only stops when it sees a newline character (\ ). Name your main class Hw5pr3 and your main file Hw5pr3.java.
Solution
Hi, Please find my implementation.
Please let me know in case of any issue.
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class Hw5pr3 {
public static void main(String[] args) throws FileNotFoundException {
// reading input file name
Scanner input = new Scanner(System.in);
System.out.print(\"Enter input filename : \");
String fileNamne = input.next();
// opening file
Scanner scanner = new Scanner(new File(fileNamne));
// creating 2-D array of string
String[][] records = new String[100][2];
int row = 0;
// reading file and storing in array
while(scanner.hasNext()){
records[row][0] = scanner.next(); // reading year
records[row][1] = scanner.nextLine(); // reading team name
row++;
}
scanner.close();
// now reading from user and searing team name
String year;
System.out.print(\"Enter year: \");
year = input.next();
while(! year.equalsIgnoreCase(\"stop\")){
int i= 0;
for(i=0; i<row; i++){
if(records[i][0].trim().equals(year)){
System.out.println(\"Winning Team: \"+records[i][1]);
break;
}
}
// if year is not in array
if( i == row){
System.out.println(year+\" not present in record\");
}
// reading next year
System.out.print(\"\ Enter year: \");
year = input.next();
}
}
}
/*
Sample run:
Enter input filename : input.txt
Enter year: 1990
Winning Team: San Francisco 49ers
Enter year: 2000
Winning Team: St. Louis Rams
Enter year: 2020
2020 not present in record
Enter year: stop
