String Methods

• length: counts the number of characters in a string

  String greeting = "Hello, World!";
  int n = greeting.length(); // sets n to 13

• toUpperCase: creates another String object that contains the characters of the original string, with lowercase letters converted to uppercase

  String river = "Mississippi";
  String bigRiver = river.toUpperCase(); // sets bigRiver to "MISSISSIPPI"

• When applying a method to an object, make sure method is defined in the appropriate class

  System.out.length(); // This method call is an error
