fileinputstream

Differences between fileinputstream and filereader Core tips: 1) File class introduction File class encapsulates the function of operating the file system on the user's machine. For example, you can use the File class to obtain the last modification time, move the object, or delete or rename the object. In other words, the stream class focuses on the file content, while the file class focuses on the main methods for storing files on disks: (), Last

I. How to read and write files reads a file through a stream. A stream is a series of flowing characters that send an information channel in a first-in, first-out manner. ii. Classification of Java streams to divide by the flow direction 1. Output stream OutputStream and writer as base class 2. Input stream InputStream and reader as base class input and output are relative to computer memory. divided by processing data units 1, Byte stream ⑴ byte input stream, InputStream base class;

Before explaining the specifics of FileInputStream and FileReader in Java, I want to talk about the fundamental differences between InputStream and Reader in Java, and when to use InputStream and reader respectively. In fact, InputStream and reader are abstract classes and do not directly read data from a file or socket. However, the main difference between them is that InputStream is used to read binary data (Byte stream mode, translator note), reade

Read and write to the file is always my weak link, this is caused by the wrong learning habits: each course I began to learn very seriously, so the foundation is relatively solid point; but then the more the more relaxed, so the next one becomes blurred, and the Java curriculum I/O Also put in the back position to introduce, so this piece of learning is not good ... This morning I was looking at "Ivor Horton's beginning Java 2, JDK 5 Edition" ("Java 2 Getting Started"), and wrote several example

Preface:For files in the file system, you can use the FileInputStream stream class to read in binary form, but because Java itself is positioned above the JVM, it does not have the ability to handle the underlying computer, Therefore, some of the methods involved in the underlying processing are processed using the native method to invoke the third-party underlying language.I re-explain the internal implementation of the

java.io There are two abstract classes: InputStream and ReaderInputStream is a superclass of all classes that represent byte input streamsReader is an abstract class for reading stream of charactersThe InputStream provides a byte stream reading, not a text read, which is fundamentally different from the reader class.That is, read by reader is a char array or string, using InputStream to read a byte array.Figure out the fundamental differences between the two superclass, and then look at the use

The difference between the FileInputStream class and the FileReader class:The form and parameters of the constructors for two classes are the same, the arguments are file objects, or the string that represents the path, what is the difference between them?? Readers and writers work is only on line based character data, so plain text files.For anything else, you must use Streams.? JDK5 API:FileInputStream is meant for reading streams of raw bytes such
