使用进程运行shell命令时的java块

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class ShellCommandExample {
    public static void main(String[] args) {
        try {
            // 创建进程并执行Shell命令
            Process process = Runtime.getRuntime().exec("shell command");

            // 获取命令执行的输出结果
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }

            // 等待命令执行完成
            int exitCode = process.waitFor();
            System.out.println("命令执行完成，退出码：" + exitCode);

        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
