    Default String if-else not executing

    hello,

    As you can see I am new to Java and would like some help with this problem. I've tried to solve it myself first but the issue that I'm having is I don't have the knowledge to know what I am doing wrong.

    // create a program that will say "Name" and then allow the useer's input of "their name" 
    // and then another response from the programme.
     
    import java.util.Scanner;
     
    public class HomeProject
    {
      public static void main(String[] args)
      {
    	 String yourName;
    	 String answer;
         String answer2 = "good, well have a nice day!";
    	 String answer3 = "unlucky, well have a nice day anyway!";
     
    	  Scanner input = new Scanner(System.in);
     
    	  System.out.println("What is your name?");
    	  yourName = input.nextLine();
    	  System.out.println();
     
    	  System.out.println( "Hello " + yourName + ", are you feeling well?" );
    	  answer = input.nextLine();
    	  System.out.println();
     
     
          if ("are you feeling well?".equals("yes"))
          {
          System.out.println(answer2);   
          answer2 = input.nextLine();
          System.out.println();
          }
     
          else if ("are you feeling well?".equals("no"))
              {
        	  System.out.println(answer3);   
              answer3 = input.nextLine();
              System.out.println();          }  
     
            input.close();
    	  }    
    }

    Any help will be appreciated and I'm sure its just something simple that I haven't properly understood.

    Thanks!

     if ("are you feeling well?".equals("yes"))
    The above compares two Strings that are not the same. It will never be true.
    Normally you compare the contents of a variable that has received a value from the user with one of the expected user inputs:
     input.equals("expected answer here")
    If you don't understand my answer, don't ignore it, ask a question.

    Thank you, the code has been changed to input.

     
    import java.util.Scanner;
     
    public class HomeProject
    {
      public static void main(String[] args)
      {
    	 String yourName;
    	 String answer;
         String answer2 = "good, well have a nice day!";
    	 String answer3 = "unlucky, well have a nice day anyway!";
     
    	  Scanner input = new Scanner(System.in);
     
    	  System.out.println("What is your name?");
    	  yourName = input.nextLine();
    	  System.out.println();
     
    	  System.out.println( "Hello " + yourName + ", are you feeling well?" );
    	  answer = input.nextLine();
    	  System.out.println();
     
     
          if (input.equals("yes"))
          {
          System.out.println(answer2);   
          answer2 = input.nextLine();
          System.out.println();
          }
     
          else if (input.equals("no"))
              {
        	  System.out.println(answer3);   
              answer3 = input.nextLine();
              System.out.println();          }  
     
            input.close();
    	  }    
    }

    The code used to have input.equals... but from messing around with it I had made it worst. However it still seems like the 'if' and 'if else' statement is not being recognised and still isn't giving me "yes" = good, have a nice day or "no" = unlucky, have a nice day anyway.

    thank you for responding, do you have any ideas with what else I am doing wrong?

    Default Re: String if-else not executing

    What variable is the input from the user read into using the Scanner class's nextLine() method?

    The input variable contains the reference to a Scanner object.
    You need to compare the variable that holds the users input against the expected answers.
    If you don't understand my answer, don't ignore it, ask a question.
