java - The number occurrence of a character is to be counted in a given line string. Can anyone point out where the error is? The code compiles correctly -

-

the idea count number of occurrence of given character user inputs in line of string imputed user. idea use recursion in java rather sort of loop. code compiles correctly , runs correctly. result not give correct answer (does not count asked character correctly in given line of string.) can point out?

import java.util.scanner;  public class numberofletters {      public static int lettercounter(string line, string x)      {         if(line.isempty())         {             return 0;         }         else          {             if(line.charat(0) == 'x')             {                 return 1 + lettercounter(line.substring(1), x);             }             else              {                 return 0 + lettercounter(line.substring(1), x);             }         }     }         public static void main(string[] args)     {         scanner keyboard = new scanner(system.in);                system.out.println("enter line of string >_ ");         string inputline = keyboard.nextline();          system.out.println("enter character count >_ ");         string charac = keyboard.nextline();                  int count = lettercounter(inputline, charac);          system.out.println("the number of '"+ charac + "' in input '"+ inputline + "' "+ count);         keyboard.close();     } }

you're testing 'x' instead of variable:

if(line.charat(0) == 'x')

you need:

if(line.charat(0) == x)

also pass x in char instead of string.
