如何在Java中检查进程是否已启动

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

public class ProcessChecker {
    public static void main(String[] args) {
        String processName = "your_process_name"; // 替换为目标进程的名称

        if (isProcessRunning(processName)) {
            System.out.println("进程已启动");
        } else {
            System.out.println("进程尚未启动");
        }
    }

    public static boolean isProcessRunning(String processName) {
        try {
            Process process = Runtime.getRuntime().exec("tasklist"); // Windows系统下获取进程列表的命令
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                if (line.contains(processName)) {
                    return true;
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return false;
    }
}
