This class provides thread-local variables. These variables differ from their normal counterparts in that each thread that accesses one (via its get or set method) has its own, independently initialized copy of the variable. ThreadLocal instances are typically private static fields in classes that ...
Note that Figure 5-9 shows that the first parameter in the local variables for runInstanceMethod() is of type reference, even though no such parameter appears in the source code. This is the hidden this reference passed to every instance method. Instance methods use this reference to access ...

If the declaration denotes an instance variable of a class C (8.3.1.1), the expression name must appear within an instance method (8.4.3.2), instance variable initializer (8.3.2), instance initializer (8.6), or constructor (8.8). If the expression name appears within a static type ...
