如何把我的切换按钮值转换成int

这里是我的简单的计算器code.Im尝试添加该代码的东西special.I希望这个程序：它只会用2级的偶数或2个奇数四个算术运算。举例来说，如果用户试图点击偶数，并在同一时间奇数，我的代码将警告像"You can click 2 even numbers or 2 odd numbers"。怎么我可以使用点击值通过切换按钮int和使用if(value%2==0)声明？如何把我的切换按钮值转换成int

那么，有什么问题呢？你想获得按钮的值？那是对的吗？ –

是的，这是正确的。 – cansukartal

请张贴的完整代码 –

JToggleButton具有两个状态，测试与被要求复位的JToggleButton.setSelected(false)状态下执行代码后JToggleButton.isSelected
，因为鼠标/关键事件与切换JToggleButton
JToggleButton（JOptionPane.showMessageDialog(this, "You cant click 3 buttons at the same time.."); ）不是正确计算器JComponent（0-9，+ - =），使用JButton代替，there are various and different ways how to do it an properly，开始ActionCommand或put/getClientProperty

因此我不能用JToggleButton编写代码？我必须使用JToggleButton中，但心不是问题尚未解决 – cansukartal

一个简单的计算器，我推荐使用Jbutton将相对于JToggleButtons。随着Jbutton将，你可以简单地使用：

StringBuilder intbuilder = new StringBuilder(); 
int firstnumber; 
int secondnumber; 
String operation; 
button5.addActionListener(new ActionListener(){ 
    public void actionPerformed(ActionEvent e) 
    { 
     intbuilder.append("5"); 
    } 
}); 
multiplybutton.addActionListener(new ActionListener(){ 
    public void actionPerformed(ActionEvent e) 
    { 
     firstnumber = Integer.parseInt(intbuilder.toString()); 
     operation = "*"; 
    } 
});

而且一旦等号被按下时，只是对视字符串操作两个数执行该操作。

I'he尝试，但是当我使用Jbutton将代码想不出运行valueCheck一部分，所以我不能改变JToggleButtons到Jbutton将 – cansukartal

随着Jbutton将你不需要的setSelected（假的），也不您遇到了一次选择两个以上按钮的问题。 JButton几乎完全使valueCheck方法过时。 –

首先，我在手机上写了这个。那里肯定会有一些错字。其次，我写它来帮助，而不是用勺子代码。你在那里得到我说的。当然，它不会编译。他们的按钮命名为“multiplybutton”的机会是多少？ –
