thank answers ! 1 more question: how print out boolean value? system.out.println(goodbase) not seem work

public class dna {       public static void main(string[] args){       abase('a');      }        public static boolean abase (char c) {                          char [] chararray = { 'a', 'g', 'c', 't' };         boolean goodbase;          if (c == 'a' || c == 'g' || c == 'c' || c == 't')          {           return true;              }          else          {           return false;         }       }       } 

thanks !

the code working me if use in right environment. have attached complete functioning sample below:

public class main {      // create test method     public static boolean test(char c) {         if (c == 'a' || c == 'g' || c == 'c' || c == 't') {             return true;         } else {             return false;         }     }      public static void main(string[] args) {          // create sample data         string sample = "agctedhi";          // test         (int = 0; < sample.length(); i++) {             char current = sample.charat(i);             system.out.println(current + " " + test(current));         }      } } 

output:

a true g true c true t true e false d false h false false
