10.4    Local Classes

Local classes are also inner classes, but these classes aren’t simply set like a property in the body of a class. Instead, you’ll directly define local classes in statement blocks consisting of methods, constructors, and initialization blocks. Local interfaces aren’t possible.

10.4.1     Example with a Custom Declaration

In the following example, the main(...) method declares an inner class named Snowden with a constructor that accesses the final variable PRISM :

public class NSA {  public static void main( String[] args ) {    
                final int PRISM = 1;    int tempora = 2;    tempora++;                          // (*)    
                class Snowden {      Snowden() {        System.out.println( PRISM );//        System.out.println( tempora ); // 
                     Commented out a compiler error      }    }    new Snowden ...
