使用JAVA关于进程信息查询

如何用JAVA代码写出查询进程的基本信息如pid，ppid，C

import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.nio.charset.Charset;

public class ProcessUtil {
    
    
    public static void main(String[] args) throws Exception {
        
        // 创建系统进程
        ProcessBuilder pb = new ProcessBuilder("tasklist");
        Process p = pb.start();
        BufferedReader out = new BufferedReader(new InputStreamReader(new BufferedInputStream(p.getInputStream()), Charset.forName("GB2312")));
        BufferedReader err = new BufferedReader(new InputStreamReader(new BufferedInputStream(p.getErrorStream())));
        System.out.println("Window 系统进程列表");
        String ostr;
        
        while ((ostr = out.readLine()) != null)
        System.out.println(ostr);
        String estr = err.readLine();
        if (estr != null) {
        System.out.println("\nError Info");
        System.out.println(estr);
        }
    }

}
