How do I handle file I/O in Python and Java?

In Python, you can use the built-in open() function to read and write files. For example, to read a file, you can do:

with open('file.txt', 'r') as file:
    content = file.read()

In Java, you can use FileReader and BufferedReader for reading files. Here's a simple example:

import java.io.*;

public class FileReadExample {
    public static void main(String[] args) {
        try (BufferedReader br = new BufferedReader(new FileReader("file.txt"))) {
            String line;
            while ((line = br.readLine()) != null) {
                System.out.println(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

What about writing to files in both languages?

In Python, you can write to a file using the open() function with the 'w' mode:

with open('file.txt', 'w') as file:
    file.write('Hello, World!')

In Java, you can use FileWriter for writing:

import java.io.*;

public class FileWriteExample {
    public static void main(String[] args) {
        try (FileWriter writer = new FileWriter("file.txt")) {
            writer.write("Hello, World!");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Are there any differences in error handling between the two?

Yes, in Python, you typically use try-except blocks for error handling, while in Java, you use try-catch blocks. For example:

In Python:

try:
    with open('file.txt', 'r') as file:
        content = file.read()
except FileNotFoundError:
    print('File not found!')

In Java:

try {
    BufferedReader br = new BufferedReader(new FileReader("file.txt"));
} catch (FileNotFoundException e) {
    System.out.println("File not found!");
}
