Strings in Java are objects of the String class that hold sequences of characters.
String objects can be created by using string literals (String s = “hi”;) or by calling the String class constructor (String t = new String(“bye”);).
new is used to create a new object of a class.
null is used to indicate that an object reference doesn’t refer to any object yet.
String objects can be concatenated using the + or += operator, resulting in a new String object.
Primitive values can be concatenated with a String object. This causes implicit conversion of the values to String objects.
Escape sequences start with a backslash \ and have special meaning in Java. Escape sequences used in this course include ", \, and \n to print out a quote, backslash, and a new line.
