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?

Answer 1

是的，静态块和静态字段初始化按照在输入文件中找到它们的顺序执行。

Answer 2

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;
        }  

Answer 3

order of initialization is different

first: you define static block before variable declaration

second: you define static block after variable declaration
