Java File Splitting: Read and Split Files by Lines

In Java, you can use the BufferedReader class to read a file line by line and use the split() method of String to split each line’s content. Here is an example code:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class Main {
    public static void main(String[] args) {
        try {
            BufferedReader reader = new BufferedReader(new FileReader("file.txt"));
            String line;
            while ((line = reader.readLine()) != null) {
                String[] parts = line.split("\\s+"); // 使用空格拆分每一行的内容
                for (String part : parts) {
                    System.out.println(part);
                }
            }
            reader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

In the code above, we first create a BufferedReader object to read the file “file.txt”, and then use a while loop to read the contents of the file line by line. In each line, we use the split(“\s+”) method to split the content of each line using a space as a delimiter, and store the split results in a String array. Finally, we iterate through this array and print each part.
