Go JAVA accesses internal classes, methods, and so on in main

1. Using static properties, methods, inner classes

1 classA2 {3     Static inti = 1;//static properties of Class A4     Static voidOutPut ()//static methods for Class A5     {6 System.out.println (i);7     }8     Static classB//static inner class of Class A9     {Ten         voidOutPut () One         { ASystem.out.println ("B"); -         } -     } the      Public Static voidMain (string[] args) -     { -          -System.out.println (i);//calling a static property +OutPut ();//calling a static method -b b =NewB ();//calling a static inner class + b.output (); A     } at}

2. Use the object name of this class to access

1 classA2 {3     inti = 1;//Properties4     voidOutPut ()//Method5     {6 System.out.println (i);7     }8     classB//Inner class9     {Ten         voidOutPut () One         { ASystem.out.println ("B"); -         } -     }     theB Newb ()//(key) to create a B object in a dynamic method -     { -b b =NewB (); -         returnb; +     }     -      Public Static voidMain (string[] args) +     { AA A =NewA (); atSystem.out.println (A.I);//Call Properties -A.output ();//Calling Methods -b b = A.newb ();//calling inner class - b.output (); -     } -}

In static main, you cannot create a non-static inner class.
