TXT 파일을 수신하여 읽고 저장하는 생성자

당신이 3 개 텍스트 파일을 말해봐 text1.txt, text2.txt그리고 text3.txt다음과 같은 내용으로 :

text1.txt :

A B C D E F G H I J 

text2.txt :

A B C D E F G H I J K L M N O

text3.txt :

A B C D E F G H I J K L

당신은 만들 수 있습니다 Text구현 Comparable<Text>:

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;

public class Text implements Comparable<Text> {
    private final String fileName;
    private String fileData;
    private int wordCount;

    public Text(String filePath) {
        File file = new File(filePath);
        this.fileName = file.getName();
        try {
            BufferedReader bufferedReader = new BufferedReader(new FileReader(filePath));
            StringBuilder sb = new StringBuilder();
            String line = bufferedReader.readLine();
            int wordCount = 0;
            while (line != null) {
                wordCount += line.split(" ").length;
                sb.append(line);
                sb.append(System.lineSeparator());
                line = bufferedReader.readLine();
            }
            this.fileData = sb.toString().strip();
            this.wordCount = wordCount;
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public String getFileData() {
        return this.fileData;
    }

    @Override
    public String toString() {
        return String.format("%s [%d]", this.fileName, this.wordCount);
    }

    @Override
    public int compareTo(Text t) {
        if (this.wordCount == t.wordCount) {
            return this.fileData.compareTo(t.getFileData());
        }
        return this.wordCount - t.wordCount;
    }
}

사용 예 :

$ javac TestText.java Test.java
$ java TextText text1.txt text2.txt text3.txt
[text1.txt [10], text2.txt [15], text3.txt [12]]
[text1.txt [10], text3.txt [12], text2.txt [15]]
