Question

我想创建一个启动Textfield的程序。在Textfield中，我可以编写将要启动的命令另一个过程。

实施例： Textfield：＆＃34;打开firefox olaf＆＃34; 然后程序启动firefox。奥拉夫就是那个信号命令结束。

我的程序比较Textfield String数组使用命令String数组，例如这个词＆＃34;打开＆＃34;在两个字符串数组中都相等在开关案例方法中，以下方法＆＃34;打开＆＃34;。这很好。

我的问题：现在我想要这样的命令： Textfield：＆＃34;输入firefox www.web.de olaf＆＃34; 该程序应该专注于Firefox，并应该在Firefox中输入＆＃34; www.web.de＆＃34;，但我不知道该怎么做。我不想用机器人课 robot.keyPressed()

此外，我想输入网站的文本字段。

为什么我这样做？我只想学习java并使用语音演讲，所以我不需要键入＆＃34;打开firefox olaf＆＃34;。我可以说它;）

如果我需要使用C ++，那没关系

            robot.delay(1000);

            this.requestFocus();                                //set focus on KeyEventClass after start process

            } catch (Exception x) {System.out.println("Error to starts process:"+x);}

    }

    public void keyTyped(KeyEvent e) {
    }

    @Override
    public void focusGained(FocusEvent arg0) {  
    }

    @Override
    public void focusLost(FocusEvent arg0) {
        // TODO Auto-generated method stub
    }

}

您可以使用命令行参数来实现此目的。

./ firefox www.stackoverflow.com

所以你可以使用ProcessBuilder传递它：

String urlAddress = someJTextField.getText();
ProcessBuilder pb = new ProcessBuilder("/firefox", urlAddress);
pb.start();

发送命令进行处理
