所以我有以下代码，我正在努力浓缩我创造的if else海。我不知道如果有可能帮助我这个：p。如果我需要提供更多信息，请询问。

我同意azurefrog。在您拥有重复代码的任何地方，尝试将该代码放入要调用的函数/方法中。您的代码将更短且可读。放入方法
的代码示例if (yes == JOptionPane.YES_OPTION) {
for (int cntr2 = 0; cntr2 < 9; cntr2++) {
gridButtons[cntr2].setText("");
gridButtons[cntr2].setEnabled(true);
grid[cntr2] = ' ';
}
count = 0;
sign = 0;
FormPanel formPanel = new FormPanel();
formPanel.firePvp();
return;
}
