java如何获取本地操作系统进程列表

 

package com.wa.xwolf.sblog.util;
 
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);
  }
 }
 
}
