Java basics-pointing to a final modified reference variable

Source: Internet

A final-modified reference variable cannot point to another object once it has been initialized, then the contents of the object to which the reference variable points are variable? Look at the following example:

 Public class Test {    publicstaticvoid  main (string[] args)  {        final  New  MyClass ();        System.out.println (+ +myclass.i)     ; class MyClass {    publicint i = 0;}

This code can be successfully compiled and has output results, the output is 1. This means that after the reference variable is final decorated, it cannot point to another object, but the contents of the object it points to are mutable.
