class LX5_3{
public static void main(String[] args) throws java.io.IOException {
byte buffer[]=new byte[10];
System.out.println("从键盘输入不超过10个字符，按回车键结束输入：");
int count =System.in.read(buffer);//读取输入的字符并存放在缓冲区buffer中
System.out.println("保存在缓冲区buffer中元素的个数为："+count);
System.out.println("buffer中各元素的值为：");
for (int i=0;i<count;i++){
System.out.print(" "+ buffer[i]);//在屏幕上显示buffer元素的值
}
System.out.println();
System.out.println("输出buffer字符元素：");
System.out.write(buffer, 0, buffer.length);
}
}
为什么我输入1234后输出的是6？
