Unable to do static import

//interface1.java

package package1;
   public interface interface1 {
      static final int a =10;
   }

//StaticImportTest.java

 import static package1.*;         //import package1.*; works

   class StaticImportTest {
      public static void main(String args[]) {
        System.out.println(a);     //System.out.println(interface1.a) works
      }
   }

when i am replacing the word "import static" with only "import" and using System.out.println(interface1.a) it works, but not sure why its not working in its current form.

For your static import to work the way you intended it would have to be import static package1.interface1.* or import static package1.interface1.a
A static import imports public static members of a class either all with * or a specific one like for example a.
A import on the other hand imports a package or specific classes from a package.

Your import static package1.* would try to import all members from the class package1 in the root package.

Making it a normal import and accessing a via interface1.a works because the import imports all classes from the package1 including interface1, therefor you can access a via the interface1 class.
