The String class is immutable, so that once it is created a String object cannot be changed.
String Length
The length() method, returns the number of characters contained in the string object.
charAt() Returns the character located at the specified index

■ concat() Appends one String to the end of another ( "+" also works)

■ equalsIgnoreCase() Determines the equality of two Strings, ignoring case

■ length() Returns the number of characters in a String
■ replace() Replaces occurrences of a character with a new character
■ substring() Returns a part of a String
■ toLowerCase() Returns a String with uppercase characters converted

■ toString() Returns the value of a String

■ toUpperCase() Returns a String with lowercase characters converted

■ trim() Removes whitespace from the ends of a String
