java swing manual start an event without user input
问题
我想在不点击所有按钮界面的情况下触发一个事件。
例如，当我点击button_0时，它将打印红色，并在同一时间执行button_1和button_2上的动作，因此也会同时打印蓝色和绿色。
这三个操作必须分开进行，因此合并这两个操作的解决方案不适用于我的情况，我只是制作了一个小指南示例。
public void actionPerformed(ActionEvent e)
{
if(e.getSource()==button_0)
{
System.out.println("红色");
}
else if(e.getSource()==button_1)
{
System.out.println("蓝色");
}
else if(e.getSource()==button_2)
{
System.out.println("绿色");
}
}
英文:
I want to activate an event without clicking all the button interface.
ex. when i click button_0, it will print red, and at the same time it will perform action on button_1 and button_2, hence will also print blue and green at the same time.
Those three operation must be separate, solution as merging both action is not applicable on my case, I only made the example as a small guide.
public void actionPerformed(ActionEvent e)
{
if(e.getSource()==button_0)
{
System.out.println("red");
}
else if(e.getSource()==button_1)
{
System.out.println("blue");
}
else if(e.getSource()==button_2)
{
System.out.println("green");
}
}

这是一种不太规范的做法：
public void actionPerformed(ActionEvent e)
{
if(e.getSource()==button_0)
{
System.out.println("红色");
button_1.doClick();
button_2.doClick();
}
else if(e.getSource()==button_1)
{
System.out.println("蓝色");
}
else if(e.getSource()==button_2)
{
System.println("绿色");
}
}
英文:
Here's a dirty way to do it:
public void actionPerformed(ActionEvent e)
{
if(e.getSource()==button_0)
{
System.out.println("red");
button_1.doClick();
button_2.doClick();
}
else if(e.getSource()==button_1)
{
System.out.println("blue");
}
else if(e.getSource()==button_2)
{
System.out.println("green");
}
}
