in particular, some classes have a special relationship with the java programming language. Examples include classes such as Object, Class, ClassLoader, String, Thread and the classes and interfaces in package java.lang.reflect, among others.
the java programming language is also a strongly typed language, because types limit the values that a variable can hold or that an expression can produce, limit the operations supported on those values, and determine the meaning of operations.strong static typing helps detect errors on compile time.
