Java I/O-Stream

In diesem Tutorial werden wir Java Eingabe/Ausgabestrom und deren Typen.

In Java sind Streams eine Sequenz von Daten, die von der Quelle gelesen und ins Ziel geschrieben werden.

class HelloWorld {
　　　　public static void main(String[] args) {
　　　　　　　　System.out.println("Hello, World!");　
　　　　}
}

For example, in our firstHello WorldIn the example, we have used System.out to print strings. Here, System.out is an output stream.

Similarly, there are input streams that receive input.

We will learn about input and output streams in detail in the following tutorials.

Stream Types

According to the data contained in the stream, it can be classified as:

• Byte Streams (Byte-Stream)

• Character Streams (Zeichenstrom)

Byte Streams (Byte-Stream)

Byte streams are used to read and write individual bytes (8data in bits).

All byte stream classes are derived from the basic abstract classes called InputStream and OutputStream.

Character Streams (Zeichenstrom)

Character streams are used to read and write individual data characters.

All character stream classes are derived from the basic abstract class Reader and Writer.
