CharBuffer.put()没有工作

Question

我尝试将一些字符串CharBuffer与CharBuffer.put()函数放在一起,但缓冲区留空.

我的代码:

CharBuffer charBuf = CharBuffer.allocate(1000);
for (int i = 0; i < 10; i++) 
{
    String text = "testing" + i + "\n";
    charBuf.put(text);
}
System.out.println(charBuf);

我尝试使用clear()或rewind()之后allocate(1000)但没有改变结果.

放入物品后必须倒带，试试这个

CharBuffer charBuf = CharBuffer.allocate(1000);
for (int i = 0; i < 10; i++) 
{
    String text = "testing" + i + "\n";
    charBuf.put(text);
}
charBuf.rewind();
System.out.println(charBuf);
