java - Could any one please point out the mistake in the IF statement -

I am very new to Java and can detect the problem with IF statement

 < Code> Class SpaceRivor {Public static zero main () {string is maximum = "This is an exam"; Four [] mfl = most fmos Charaire (); {Char current = mfl [dex] for (int dex = 0; dex & lt; mfl.length; dex ++); If (current! = "") {System.out.print (current); } Else {System.out.print ("."); }} System.out.println (); }}    
 
 
 Looking at the name and code of the class provided, I agree  
 Your problem is in queue  
  If (current! = "") {  
 First of all, this is a place No, this is an empty string. Secondly, you should compare it to a character.  
 It should be like this:  
  if (current! = '') {
