    Default if statement help

    public class christmas {
    	public static char songNumber (int songResult){
    		char song;
    	if (songResult = 1){
    		song = 'A Partridge in a Pear Tree';   **this is the line with the error, it says invalid character constant where the 'A is
    	}else (songResult = 2){
    			song = '2 Turtle Doves and a Partridge in a Pear Tree';
    		}
    			return song;
    	}
     
    	public static void main(String[] args) {
    	christmas rc = new christmas ();
     
    	char yourSong = songNumber(1);
    	System.out.println("On the" + yourSong);
    	}
    }
    I have highlighted the error in the code at about the sixth line
    Why have I got an error? I need help quick!

    Thanks

    Char variables only contain a single character, and they are defined like 'a', 'b', or 'c'.

    Strings can contain any number of characters and are defined in "double quotes", not 'single quotes'.

    Also, your if statement is assigning 1 to your songResult variable, not checking whether your songResult variable is 1. Use == instead.

    Also also, you should really use standard naming conventions and correct indentation.

    Instant fix, thank you!

    Further question though, if I was to carry on with the code with the song, say the outcome is 4 which will add a next line, is it possible to display 4 and 3 together instead of writing loads of text? I know I haven't explained that well!

    Thanks again.

    I'm not really sure what you're asking. Are you just asking about the || operator? Recommended reading: Equality, Relational, and Conditional Operators (The Java™ Tutorials > Learning the Java Language > Language Basics)

    Still slightly confused.

    What I was is say if the result was say 2, I want the number below 2 to be shown as well, so I'd want the 2 and 1 results to both be displayed

    I suggest writing out the rules that you want to determine what gets printed out. If you can't explain it in English (in a list of rules, not vague descriptions or examples), then you won't be able to write it in code.

    Hint: You can have two if statements, one after the other, without using the else keyword. Something like:

    if(x > 0){
       System.out.println("X is greater than zero!");
    }
    if(x > 10){
       System.out.println("X is greater than ten!");
    }

    If x is, for example, 15, then both print statements will be triggered. If x is 5, only the first one will be triggered.
