    Default What's wrong with my code?

    class DataTypes {

    public static void main(String[] args) {
    char letter = 'M';
    String title = "Java In Easy Steps";
    int num = 365;
    float decimal = 98.6f;
    boolean result = true;
    System.out.println("Initial is" + letter);
    System.out.println("Book is" + title);
    System.out.println("Days are" + number);
    System.out.println("Temperature is" + decimal);
    System.out.println("Answer is" + result);

    }

    }

    This is the error I get below...

    Exception in thread "main" java.lang.Error: Unresolved compilation problem:
    number cannot be resolved to a variable

    at DataTypes.main(DataTypes.java:12)

    The variable 'number' is unknown. Did you mean 'num'?

    Thanks. I did the num thing. I got it right, but how do I get things not to run into each other? There should be a space between answers. Everything is stuck together. Thanks again.

    You have to manually add a space where you want one
    if:
    System.out.println("Initial is" + letter);
    gives:
    Initial isM
    ...how did you get a space between 'Initial' and 'is'?
