如果/ else if / else in while循环自动打印else函数

Question

Java初学者。使用以下代码，我的其他功能会自动打印。所以即使在回答问题之前，你想和你的伴侣一起买房子吗？输入是/否＆＃39;它已经抛出了其他功能。

//How much is the gross salary
    boolean partner;
    String partnerQuestion;
    double partnerSalary =0;
    System.out.print("Do you want to buy the house with your partner? Type Yes / No \n");
        while(true){
            partnerQuestion = sc.nextLine().trim().toLowerCase();
            if(partnerQuestion.equals("yes")){
                //how high is the loan                
                System.out.print("What is your partners´ anually gross salary? \n");
                partnerSalary = sc.nextDouble();
                partner = true;
                break;
            } 
            else if(partnerQuestion.equals("no")){
                partner = false;
                break;
            }  
            else{
                System.out.print("I did not understand you. Please try again.");
            }
        }

为了给出一个好的图片，我在这个while循环中的if / else确实有效。

boolean timeTF;
    double term;
    System.out.print("For how many years should the mortgage run? Choose between 10/15/20/25/30 \n");
        while(true){
            term = sc.nextDouble();
            if(term != 10 && term != 15 && term != 20 && term != 25 && term != 30){
                System.out.print("Please type 10/15/20/25/30, other values are not valid \n");
                timeTF = true;   
            } 
            else{  
                timeTF = false;
                break;
            }
        }

所以我的问题是，我错过了什么？提前谢谢。
