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

try this, it works fine inside an inner class:

public static final String  s="123";

I don't know the reason why it is allowed.
