Question

Q1.

Write a IO class that prompts a user for a text file. The text file name may be passed as an argument to your program. The text file may contain one or more strings per line such as:

Course Java

Hello

Your name

Good bye

The strings on the same line can be separated by space(s) and/or tabs. Your goal is to reproduce all the strings that you read from the file. For added fun you can print them in reverse such as %u201ColleH%u201D for %u201CHello%u201D. For super programming fun you can print them in the reverse order of appearance, e.g. the above would be printed as:

eyb dooG

eman rouY

olleH

avaJ esruoC

Q2.

Implement bubble sort, like we did insertion sort in class.

Explanation / Answer

Here is the code you need... It also takes the filename from the user .

It is fully working :)

import java.io.BufferedReader;

import java.util.Scanner;

import java.io.FileReader;

import java.io.IOException;

public class ReadData {

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

Scanner in = new Scanner(System.in);

System.out.println("ENTER THE FILE PATH");

s = in.nextLine();

String file = s;

BufferedReader bufferedReader = new BufferedReader(new FileReader(file));

String line;

int lineNumber=0;

String[] lineContents = new String[100];

int i = 0;

while ((line = bufferedReader.readLine()) != null) {

++lineNumber;

lineContents[i]= line;

i++;

}

bufferedReader.close();

for (int j = lineNumber-1; j >= 0; j--){

StringBuffer buffer = new StringBuffer(lineContents[j]);

buffer.reverse();

System.out.println(buffer);

}

}

}
