java获取本地操作系统进程列表详解编程语言

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); 
        } 
    } 
  
}

控制台输出：
