What are Java IO Streams?

Can you explain what Java IO Streams are?

Java IO Streams are used to read and write data to files, network connections, and other input/output sources.

What are the different types of streams in Java?

There are two main types of streams: byte streams (for binary data) and character streams (for text data).

How do I read a file using Java IO Streams?

You can use FileInputStream for byte streams or FileReader for character streams to read files in Java.

Can you give me a code example?

Sure! Here's a simple example using FileReader:

import java.io.*;

public class ReadFile {
    public static void main(String[] args) {
        try (FileReader fr = new FileReader("example.txt")) {
            int i;
            while ((i = fr.read()) != -1) {
                System.out.print((char) i);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
