Java寫入資料進txt檔案，需求：多條資料追加進檔案，且需要處理中文編碼問題。

以下程式碼只能處理向檔案新增資料的功能，但是會覆蓋掉之前的資料

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

public class Write {
    public static void main(String[] args) throws IOException {
        String word = "hahahahhahahahhah";
        FileOutputStream fileOutputStream = null
 
;
        File file = new File("F:\\test\\test.txt");
        if(!file.exists()){
            file.createNewFile();
        }
        fileOutputStream = new FileOutputStream(file);
        fileOutputStream.write(word.getBytes("gbk"));
        fileOutputStream.flush();
        fileOutputStream.close();

    }
}
 

正確例項

public class Test{
    public static void main(String[] args) throws IOException {
        String path = "F:\\test\\test.txt";
        String word = "試試";
        BufferedWriter out = new BufferedWriter(
                new OutputStreamWriter(new FileOutputStream(path,true)));
        out
 
.write(word+"\r\n");
        out.close();
    }
}
