抱歉,这是一个简单的问题,我找不到我正在寻找的内容,可能是因为我不知道关键字是什么。
例如,我有一个 read.java,当我重定向文件时,它应该能够读取名为 quotes.txt 的文件中有多少个 A:read < quotes.txt
如何从 java 中的quotes.txt 中读取?
You can use new Scanner(System.in)
. It will be available as Standard Input Stream for read
, represented by System.in
, which is a InputStream
.
You can also do
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
and use that br
.
