Initializing Library Files even Before Static Block

 private static Method

              The static initialize block will be called on loading of the class, and will have no access to instance variables or methods.

Sample Program

package com.javalearning.basic;

public class StaticInitialize {

      private static boolean a = getInitialize();

      static

      {

            System.out.println("I am inside the static block");

      }

      public static void main(String[] args) {

            if(a)

            {

                  System.out.println("Your Libraries initizalized properly");

            }

      }

      private static boolean getInitialize() {

            int a =5,b=3;

            System.out.println("Initialize libraries prior to static block and can be reused");

            if(a>b)

            return true;

            else

                  return false;

      }

}

Reason Behind

          Static variable initialized prior to static block.

final static Method

    private static boolean a = getInitialize();

      

   private final static boolean getInitialize(){

        // initialization code goes here

    }

}

Advantage

Both can be reused later if you need to re-initialize the class variable. But calling non-final methods from final static method during instance initialization can cause problems.
