你真的需要'finally‘块吗

try {
    // 可能抛出异常的代码
} catch (ExceptionType1 e1) {
    // 处理 ExceptionType1 异常
} catch (ExceptionType2 e2) {
    // 处理 ExceptionType2 异常
} finally {
    // 无论是否发生异常，都会执行的代码
}

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

public class TryCatchFinallyExample {
    public static void main(String[] args) {
        BufferedReader br = null;
        try {
            br = new BufferedReader(new FileReader("file.txt"));
            String line;
            while ((line = br.readLine()) != null) {
                System.out.println(line);
            }
        } catch (IOException e) {
            System.err.println("Error reading file: " + e.getMessage());
        } finally {
            if (br != null) {
                try {
                    br.close();
                } catch (IOException e) {
                    System.err.println("Error closing file: " + e.getMessage());
                }
            }
        }
    }
}
