我正在使用 if else 并突然寫下一些代碼， else 表示從未使用過該分支......但它應(yīng)該可以工作。聲明看起來像這樣JOptionPane.showConfirmDialog(null,full_name+"\n"+number_age+"\n"+gender+"\n"+address+ "\n"+birthday+"\n"+cell_no,"CHECK INFORMATION!",JOptionPane.YES_NO_OPTION);if(true){ JOptionPane.showMessageDialog(null,"Thank you for Entering");}else{ JOptionPane.showMessageDialog(null,"Please Retry");}

檢查JOptionPane.showConfirmDialog響應(yīng)并與JOptionPane.YES_NO_OPTION：
int answer = JOptionPane.showConfirmDialog(null,full_name+"\n"+number_age+"\n"+gender+"\n"+address+
"\n"+birthday+"\n"+cell_no,"CHECK INFORMATION!",JOptionPane.YES_NO_OPTION);
if (JOptionPane.YES_OPTION == answer)) {
JOptionPane.showMessageDialog(null,"Thank you for Entering");
} else {
JOptionPane.showMessageDialog(null,"Please Retry");
}
