I am Java beginner. I dont understand why .toLowerCase() is not working when placed in if condition.

A simple version of my code:

if ( recType.toLowerCase() == "device") {
          System.out.println("done");
      }

it works when recType= "device" ofcourse but when recType="Device", it doesnt convert it to "device" so whats inside the if condition is not implemented!!. Any ideas?

`toLowerCase()` returns a String, and strings are compared using the `equals(...)` method, not by an operator. – arkascha Apr 29 '21 at 21:02
So `if ( recType.toLowerCase().equals("device") )` ... – arkascha Apr 29 '21 at 21:04
There's also `String.equalsIgnoreCase`: `recType.equalsIgnoreCase("device")`. – Andy Turner Apr 29 '21 at 21:04
