Java can help reduce costs, drive innovation, & improve application services; the #1 programming language for IoT, enterprise architecture, and cloud computing.
示例3:使用 InputStream 中的 read读取字节流# public static void main(String[] args) throws IOException{ InputStream input = System.in;byte[] b =newbyte[1024];intlen=0; StringBuffer sb =newStringBuffer(""); while ((len= input.read(b)) !=2) { ...

lines()method read all lines from a file to stream and populates lazily as thestreamis consumed. Bytes from the file are decoded into characters using the specified charset. lines()方法从文件中读取所有行,通过流(stream)的方式读到内存。 使用指定的字符集将文件中的二进制字节解码转换为字符。
Another option to read text files is to use the Java streaming API. TheFiles.linesreads all lines from a file as a stream. The bytes from the file are decoded into characters using theStandardCharsets.UTF-8charset. Main.java import java.io.IOException; ...
FileReader(String fileName) InputStreamReader(InputStream in) //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)); BufferReader in=new BufferReader(new FileReader(name))
类加载器问题:getResourceAsStream 方法使用的是类加载器来查找资源文件。如果资源文件位于一个不同的类加载器的类路径下,可能会导致无法找到文件。你可以试试使用不同的类加载器来加载资源文件,例如通过 Thread.currentThread().getContextClassLoader().getResourceAsStream("file.txt") 方法来获取资源文件。 请根据...
