    operator > cannot be applied to java.lang.String,java.lang.String
    You can not use the > operator with objects like Strings. You need to use methods when working with objects. Read the API doc for the String class to find some methods that are useful for comparing the contents of String objects. The method will return an int value that signifies the relationship between the two Strings being compared.

    The one that is used to compare Strings.
    Look at the API doc for all the details:
