Build a comparison of recursive ideologically _ strings

String comparison

The rule for comparing the content of two strings is:

Compare each letter at the corresponding position. If one character is different, it is different. When one string is null and the other is not empty, it is different.

Use recursive methods to reproduce and compare whether the content of the two strings is the same.

Public class MyA {static boolean compare (String a, String B) {if (a. length ()! = B. length () return false; if (a. length () = 0) return true; if (a. charAt (0 )! = B. charAt (0) return false; return compare (. substring (1), B. substring (1);} public static void main (String [] args) {String s1 = "abcde"; String s2 = "abcded"; System. out. println (compare (s1, s2 ));}}
