Question

前半部分代码确定您是男性还是女性。下半部分代码的答案取决于男人还是女人。但是当我进入“男人”时，它仍会打印女人的代码。请帮忙

   Scanner scan1 = new Scanner(System.in);        
   System.out.println("Are you a man or woman?");
   String user_inputs_sex = scan1.nextLine();
   String user_sex = user_inputs_sex;   

if (user_inputs_sex.equalsIgnoreCase("MAN")) 
     {
 user_sex = man;
     }
 else if (user_inputs_sex.equalsIgnoreCase("WOMAN")
     {
 user_sex = woman;
     }

System.out.println("Having a good day?");

if ((user_answer.equalsIgnoreCase("YES")) && (user_sex.equals(woman)))
    {                                                                 
    System.out.println("Glad to hear that ma'am");
    } 
 // when I enter "man" in the previous code it still prints out this code

    else if 
   ((user_answer.equalsIgnoreCase("NO")) && (user_sex.equals(woman))) 
    {
    System.out.println("Sorry to hear that ma'am");
    } 

 // here is same code as above but for a man
