Please be informed that NONE of the design/code from this
page is claiming to be some sort of best practices and we DO NOT expect
any of our visitor/reader of this page to assume this as some sort of
best practice for any context and should not be using this 
as it is without appropriate evaluation to their, so to say, 
specific programming context.

This page intends only to provide bit and piece of known ways  for
doing some sort of example and may not be fit for any other purpose.




Advertisement : 



public class TestFinal {
  public TestFinal() {
  Test test = new Test("Test");
    test = new Test("Test12");
    System.out.println(test);
  }
  public static void main(String[] args) {
    new TestFinal();
  }
 }
  final class Test
  {
    private String tmp;
    public Test(String tmp) {
    this.tmp = tmp;
  }
   public String toString() {
   return tmp;
  }
}

In this above example, looking at the text colored green.
"Is it compilation ok code? As Test class is declared final".
Reference of variable test is changed to another instantiation
reference by the second line. If yes, WHY?





Please try this by some small sample program, and
this concept is really interesting to explore.
