将ByteBuffer转换为String是否删除位于String末尾的字符串换行符? [英] Converting ByteBuffer To String remove linebreaks of string which are located at the end of String?

问题描述

我在android studio中写了以下代码

I write the following code in the android studio

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        String hello = "Hello\n\n";
        ByteBuffer buffer2 = ByteBuffer.allocate(hello.getBytes().length);
        buffer2.put(hello.getBytes());
        buffer2.flip();
        while (true) {
            Log.d(TAG, new String(buffer2.array()));
        }
    }
}

它应该打印带有换行符的Hello，但不显示以下行截图.

It should print Hello with line breaks but as shown in the following screenshot it doesn't.

推荐答案

将ByteBuffer转换为String可以删除以下字符串的换行符:位于String的末尾?

Converting ByteBuffer To String remove linebreaks of string which are located at the end of String?

答案:否

演示:

import java.nio.ByteBuffer;

public class Main {
    public static void main(String[] args) {
        String hello = "Hello\n\n";
        ByteBuffer buffer2 = ByteBuffer.allocate(hello.getBytes().length);
        buffer2.put(hello.getBytes());
        buffer2.flip();

        System.out.println(new String(buffer2.array()) + "Hi");
    }
}

输出:

Hello
