class - Static variable initialization in java -


consider following code :

  public class testclass      {       int j=10;       static int h=j;        testclass()       {            system.out.println(h);       }        public static void main(string[] args)       {           testclass obj= new testclass();                }      }

why generates error when have declared j above h .

the error because mixing static declarations instance variable declarations (which pretty clear error message cannot make static reference non-static field j). change first initialization 

static int j = 10;

and code compiles fine.
