TIOBE - Java Coding Standard

Rule: Design12

Synopsis:	Non-static initializers are confusing
Language:	Java
Severity Level:	2
Category:	Design

Description:

A nonstatic initializer block will be called any time a constructor is invoked (just prior to invoking the constructor). While this is a valid language construct, it is rarely used and is confusing.

public class MyClass {
 // this block gets run before any call to a constructor
 {
  System.out.println("I am about to construct myself");
 }
}
