java - Can I declare inner class as a static and access it without creating an object in surrounding class? -

i read static can applied nested class.so out creating object can accessible. getting output.

string stored in str is- inside class example1 code:

class example1{   //static class   static class x{       static string str="inside class x";   }   public static void main(string args[])   {       x.str="inside class example1";       system.out.println("string stored in str is- "+ x.str);   } } 

your codes works fine, without errors.

you can access static method /field of static inner class, without creating object of static inner class. if want access non-static method/fields of static inner class class, required create object of static inner class.

class example1 {     // static class     static class x {         static string str = "inside class x";          public void display() {             system.out.println("i in display method");         }     }  }  public class staticinnerdemo {     public static void main(string[] args) { //accessing static field of static inner class         example1.x.str = "inside class example1";         system.out.println("string stored in str is- " + example1.x.str);  //accessing non static method of static inner class.         example1.x ob = new example1.x();         ob.display();      }  } 

nested classes
