Java-JRadioButton被选中

我有这样简单的支票：

boolean isPressed;


 if ((jRadioButton1.isSelected() == false) || (jRadioButton2.isSelected() == false) || (jRadioButton3.isSelected() == false)) {
        isPressed = false;
    } else {
        isPressed = true;
    }
    System.out.println(isPressed);

为什么即使我在面板中标记了RadioButton，我也总是得到false？

在if子句中必须使用and（&&）而不是or（| |）

if ((jRadioButton1.isSelected() == false) &&
      (jRadioButton2.isSelected() == false) && 
      (jRadioButton3.isSelected() == false)) {
        isPressed = false;
    } else {
        isPressed = true;
    }
    System.out.println(isPressed);

您的逻辑意味着，如果您的任意一个单选按钮未按下，则isPressed为false

试着转换一下逻辑

if ((jRadioButton1.isSelected() == true) || (jRadioButton2.isSelected() == true) || (jRadioButton3.isSelected() == true)) {
    isPressed = true;
} else {
    isPressed = false;
}
System.out.println(isPressed);

编辑：可以简化为

isPressed = (jRadioButton1.isSelected() || jRadioButton2.isSelected() || jRadioButton3.isSelected())
