java中的静态变量初始化

Question

Consider the 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 this generates error even when i have already declared j above h .

Answer 1

The error is because you are mixing static declarations with instance variable declarations (which is pretty clear from the error message Cannot make a static reference to the non-static field j ). Change the first initialization to

static int j = 10;

and your code compiles just fine.
