java - Can you see why this if statement is not working correctly? -

-

when run if statement returns false , doesn't run 2 lines have there. can see in above line checked if words same , identical. there here oblivious or screwed? if matters using eclipse. 

boolean wordhaselement = false; (int firstdimension = 0; firstdimension <= wordnumber-1; firstdimension++){     system.out.println("-"+ words[firstdimension][0] + "-" + linewords[linewordnumber]  + "-");     if (words[firstdimension][0] == linewords[linewordnumber] ){         system.out.println("worked");         wordhaselement = true;     } }

if (words[firstdimension][0] == linewords[linewordnumber] ){

should replaced with

if (words[firstdimension][0].equals(linewords[linewordnumber] ){
  • == checks see if 1 object same another, aren't interested in.
  • equals(...) checks if 2 strings hold same string -- same letters in same order -- , that's matters. or use equalsignorecase(...) if case doesn't matter.
