Cannot declare Public static final String s = new String(“123”) inside an inner class

Question

I tried to declare a class as shown below

class Outer{
    private final class Inner{
      public static final String s1 = new String(\"123\");
      public         


        

Answer 1

cf Java Language specification, second edition, §8.1.2

An inner class is a nested class that is not explicitly or implicitly declared static. Inner classes may not declare static initializers (§8.7) or member interfaces
