Expert Solution
The solution to the above problem in Java is as follows:-
I have used Buffered reader to fetch tab seprated properties:-
Code-
import java.io.*;
import java.util.Scanner;
import java.util.ArrayList;
public class PS1{
public static void main(String[] args) {
try{
BufferedReader buf = new BufferedReader(new
FileReader("cars.txt")); //using buffered reader to read
files
ArrayList<String> words = new ArrayList<>();
String lineJustFetched = null;
String[] wordsArray;
int year;
String make;
String model;
while(true){
lineJustFetched = buf.readLine();
if(lineJustFetched == null){
break;
}else{
wordsArray = lineJustFetched.split("\t"); //Splitting the fetched
line
make=wordsArray[0]; //Fetching the make
model=wordsArray[1]; //Fetching the model
year=Integer.parseInt(wordsArray[2]); //Fetching the year
System.out.printf("%15s%25s%5s\n", make,model,year);
}
}
buf.close();
}catch(Exception
e){
e.printStackTrace();
}
}
}
