Java compilers can arrange the local variables array as they wish. Compilers can place the methodís local variables into the array in any order, and they can use the same array entry for more than one local variable. For example, if two local variables...
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 ...
and they can use the same array entry for more than one local variable. For example, if two local variables have limited scopes that donít overlap, such as the i and j local variables in Example3b below, compilers are free to use the same array entry for both variables. During the fir...
Putting the keyword static in front of a local variable declaration creates a specialtype of variable, a so-called static local variable. This variabl

Declaration statements introduce a new local variable, local constant, or local reference variable (ref local). Local variables can be explicitly or implicitly typed. A declaration statement can also include initialization of a variable's value.
