在java中，如何停止从另一个方法调用一个方法？

我有一个计算器代码，问题是：

 public void valueCheck(String value,JToggleButton button) {
        if(values.size()>2) 
        {
            processValue(value);
            button.setSelected(false);
            JOptionPane.showMessageDialog(this, "You cant click 3 buttons at the same time..");
        }
    }

有一种方法valueCheck和：

public boolean evenOdd(JToggleButton buton)
    {
        if(values.size()==2)
        {
        System.out.println((String)values.get(0));
        System.out.println((String)values.get(1));

        String number1 = new String(values.get(0));
        String number2 = new String(values.get(1));

        if(evenNumbers.contains(number1))
        {
            if(evenNumbers.contains(number2))
            {
                processValue(number1);
                processValue(number2);
            }
            else if(oddNumbers.contains(number2))
            {
                buton.setSelected(false);
                JOptionPane.showMessageDialog(this, "You cant click an even and an odd number at the same time..");

            }
        }
        else if(oddNumbers.contains(number1))
        {
            if(oddNumbers.contains(number2))
            {
                processValue(number1);
                processValue(number2);
            }
            else if(evenNumbers.contains(number2))
            {
                buton.setSelected(false);
                JOptionPane.showMessageDialog(this, "You cant click an even and an odd number at the same time..");
            }
        }
        }
        return false;
    }

有一种方法很奇怪

我的问题是：我不想让valueCheck方法为evenOdd方法运行。当evenOdd方法运行时，必须停止调用valueCheck。是否存在执行此操作的事件？我想在evenOdd运行时停止调用valueCheck

这是我的全部代码
