In Java, the IO stream requires operating system resources, and the resources are freed after the use is complete.The IO stream can be divided into byte stream and character stream depending on the type of data being manipulated.The character

Java stream operations can be divided into byte streams and byte streams. 1. byte stream All read Operations inherit from a common superclass java. io. InputStream class. All write operations inherit from a common superclass java. io. OutputStream class. Both

PrintStream (print output stream) and javaprintstream in JavaPrintStream in Java (print output stream)PrintStream is a print output stream that inherits from FilterOutputStream. PrintStream is used to decorate other output streams. It can be added to other output streams so that they can easily print various data value

For example, w

. This is extremely important, it not only reduces the file space, and even if the code is not very sophisticated, there is no need to worry about an infinite loop (an example of an insensitive case where you can save objects in a recursive way without effectively auditing which objects have been saved, and then you may end up in a never-ending loop). Unfortunately, the file format defined by the Java serialization mechanism appears to be fragile, a

8. Character Stream Writer/reader the characters in Java are in the Unicode standard, one character is 16 bits, that is, one character is represented by two bytes. To do this, a stream that handles characters is introduced in Java. 1. Reader abstract class Abstract class for reading

contents of the file Ep10_1.txt)It is important to note that Java treats a Chinese or English letter as a character, a carriage return or a newline as two characters.Reading files using the BufferedReader classThe BufferedReader class is used to read the data in the buffer. You must create a FileReader class object when you use it, and then create an object of the BufferedReader class with that object as a parameter. The BufferedReader class has two

abstract class is a super class that represents all the classes of the output byte stream. The output stream accepts the output bytes and sends them to a receiver. Applications that need to define the outputstream subclass must always provide at least one method that can write one output byte. Void close ()Close the output stream and release all system resources

The IO stream in Java is used to process the data transfer from the device to the device before it is streamed in Java. Streams fall into two categories: byte stream and character stream.BYTE stream: Inputstream,outputsteam. (The data in the computer is stored in bytes, and
