Second, we’ll see how to read the content withBufferedReader,Scanner,StreamTokenizer,DataInputStream,SequenceInputStream,andFileChannel. We will also discuss how to read a UTF-8 encoded file. Finally, we’ll explore the new techniques to load and read a file in Java 7 and Java 8. This a...

Whenpackaging the application asjarfile, the file present in the'/resources'folder are copied into the root'target/classes'folder. In this case, the file location is inside a zipped archive likejar-filename.jar/!filename.txt. We should directly read this file asInputStream. ...
publicinterfaceExternalizableextendsjava.io.Serializable{voidwriteExternal(ObjectOutput out)throws IOException;voidreadExternal(ObjectInputin)throws IOException,ClassNotFoundException;} java.io.ObjectOutputStream类 表示对象输出流,它的writeObject(Object obj)方法可以对指定obj对象参数进行序列化,再把得到的字节序列写...
(1) public abstract int read( ):读取一个byte的数据,返回值是高位补0的int类型值。 (2) public int read(byte b[ ]):读取b.length个字节的数据放到b数组中。返回值是读取的字节数。该方法实际上是调用下一个方法实现的 (3) public int read(byte b[ ], int off, int len):从输入流中最多读取le...
