ProcessViewer.java 类，负责界面实现

import java.awt.BorderLayout;import java.awt.FlowLayout;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.io.IOException;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JPanel;import javax.swing.JScrollPane;import javax.swing.JTable;import javax.swing.ListSelectionModel;public class ProcessViewer extends JFrame{private BorderLayout borderlayout = new BorderLayout();private FlowLayout flowlayout = new FlowLayout(FlowLayout.RIGHT);private JPanel jpl = new JPanel();private JPanel jplbutton = new JPanel();private JTable jtable;private JButton jbutton;private JButton jbutton2;private JScrollPane jscrollPane;public ProcessViewer(){TaskList tasklist = new TaskList();tasklist.init();jtable = new JTable(tasklist.result,tasklist.title);jtable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);        jscrollPane  = new JScrollPane(jtable);        jbutton = new JButton("结束进程");        jbutton.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {String process = (String) jtable.getValueAt(jtable.getSelectedRow(), 0);try {Runtime.getRuntime().exec("taskkill /f /im "+process);} catch (IOException e1) {e1.printStackTrace();}tasklist.init();jtable.updateUI();jpl.repaint();System.out.println(process);}        });        jbutton2 = new JButton("刷新进程");        jbutton2.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {tasklist.init();jtable.updateUI();jpl.repaint();}        });jpl.setLayout(borderlayout);jpl.add(jscrollPane);jplbutton.setLayout(flowlayout);jplbutton.add(jbutton2);jplbutton.add(jbutton);this.pack();this.setTitle("进程管理器");this.add(jpl,BorderLayout.CENTER);this.add(jplbutton,BorderLayout.SOUTH);this.setBounds(400, 200, 600, 400);this.setVisible(true);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);}public static void main(String[] args) {new ProcessViewer();}}

TaskList.java 类，负责调用系统进程并生成相应格式

import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;public class TaskList {public BufferedReader br=null;public String [][] result=new String[100][5];public String [] title={"映像名称","PID","会话名","会话#","内存使用"};public void init(){Process proc;try {proc = Runtime.getRuntime().exec("tasklist /NH /FO csv");br=new BufferedReader(new InputStreamReader(proc.getInputStream())); String res=null;int x = 0;            while((res=br.readLine())!=null){                  String[] value=res.replace("\",\"", ";").replace("\"", "").split(";");                if(value.length==5){                for(int i = 0;i<5;i++){                         result[x][i] = value[i];                    }                }                x++;                if(x==100)                break;            }} catch (IOException e) {e.printStackTrace();}          }}
