Different between declaring static variable before or after static block in java

Question

The code 1:

       public class StaticBlockExample1
      {
        static {  value = 20;  }

        static int value = 10;
        public static void main(String[] args) {

              System.out.println(" Value = " + value);
        }
    }

output of StaticBlockExample1 is 10

The code 2:

  public class StaticBlockExample2 
      {
        static int value = 10;
        static {    value = 20;     }   

        public static void main(String[] args)
           {
            System.out.println(" Value = " + value);
           }
      }

output of StaticBlockExample2 is 20.

Am confused with outputs of the above examples. is there any significance to declare static variable before or after static block?

Yes, the static block and the static field initializations are executed in the order in which they are found in the input file.

The most important is order of your inicializations. - 1st case - 10 is defined as second

static int value = 10;

and in 2nd case , block is second

  static {
            value = 20;
        }

order of initialization is different

first: you define static block before variable declaration

second: you define static block after variable declaration
