java - Why "if" is not doing anything in this boolean method? - 


import java.util.scanner;//import scanner public class review{ //name of program     public static void main(string[]args){ // main statement         scanner i=new scanner(system.in);         system.out.println("enter string");         string b=i.nextline();          system.out.println("enter letter");         char c=i.next().charat(0);         system.out.println("answer "+test1(b,c));     }      public static boolean test1(string a, char b){          boolean result= true;          for(int i=0;i<a.length();i++)              if(a.charat(i)==b)                  result =true;              else                  result=false;          return result;      }  }

this program looking checking char in string or not.

hello, e = true
hello, = false

in method test1, forloop traverse whole line although finds letter string. update this:

public static boolean test1(string a, char b){          for(int i=0;i<a.length();i++) {              if(a.charat(i)==b)                  return true;          }          return false;      }

because, if letter found string don't need check further, hence:

if(a.charat(i)==b) // if condition finds true path     return true; // return true

note that, return statement causes execution leave current function or tersely current subordinate.
