Java寫(xiě)入數(shù)據(jù)進(jìn)txt文件，需求：多條數(shù)據(jù)追加進(jìn)文件，且需要處理中文編碼問(wèn)題。

以下代碼只能處理向文件添加數(shù)據(jù)的功能，但是會(huì)覆蓋掉之前的數(shù)據(jù)

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();

    }
}

正確實(shí)例

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+"
");
        out.close();
    }
}
