readLine()是BufferedReader类的一个方法,它每次从缓冲里读一行数据。 一个简单的例子: try{ //接收键盘输入作为输入流,把输入流放到缓冲流里面 BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); String aline; //从缓冲流读取一行数据 ...
n = in.read(cb, dst, cb.length - dst); //实质 } while (n == 0); if (n > 0) { nChars = dst + n; nextChar = dst; } } 从上面看出,readLine()是调用了read(char[] cbuf, int off, int len) 来读取数据,后面再根据"/r"或"/n"来进行数据处理。
new InputStreamReader(System.in));while ((line = brCleanUp.readLine ()) != null){ } System.out.println ("[输出] " + line );当while循环readLine出所有行结束时，最后一行的值就是line，这时候你输出line就可以了~while循环的这个过程是必须的，虽然while内部并未执行任何操作。Buffered...

Let’s get started and master reading a line in Java! TL;DR: How Do I Utilize the readLine() Method? ThereadLine()method must be used in conjunction with another class, such as theBufferedReaderclass. Once the class is created, you can use readLine() with the syntax,String line = rea...
readLine()读到的是换行符(回车);System.in.read(); 输入 y 和 回车 读取一个字符 'y' 然后留了一个回车换行字符！in.readLine(); 读取的就是这个回车换行字符!可以做个实验输入:(yyyyyyyyy)C:/>java judgement Do you want to modify?yyyyyyyyyyy you''ve a yyyyyyyyyy 编译...
