java - Not Entering an if Condition even if statements are valid -


my error in code though "a" , "b", "c" exist in array if condition inside inner loop doesn't recognize them. note abc string has been splitted using string.split(""); method of java

public class hexadecimal {     public static void main(string[] args)     {             string hex = "abc";             htod(hex);     }      public static void htod(string hexa)     {         string[] hexadecimal = {"0","1","2","3","4","5","6","7","8","9","a","b","c","d","e","f"};         string[] value = hexa.split("");          int deci = 0;         int bit =0;          for(int = 0; i<value.length;i++)         {             for(int j = 0; j<hexadecimal.length;j++)             {                 if(value[i] == hexadecimal[j])                 {                     deci = deci + compute(j,bit++);                     system.out.println(deci);                 }             }         }     }      public static int compute(int digit,int bit)     {         int ans = 0;         if(bit == 0)         {             ans = digit * (1);         }else         {             ans = digit * (16 * bit);         }         return ans;     } }

never compare strings ==. s1.equals(s2).

the former tests both objects same (i.e. variables reference same string object). latter tests sequences of chars of both strings same.
