Strange String comparation

I don't know why the comparation of CellType to "Hamster" is false. Wonder why it happened!

enter image description here

They are exactly the same, even in case sensitive.

Please help me.

You need to use 

if (CellType.equals("Hamster")) {
  ...
}

The other comparison checks to see if they are the same string Object, not the same string by value.

It is also a good time to lookup the differences between reference equality and Object equality.

CellType.equals("Hamster")
or
CellType.equalsIgnoreCase("Hamster")

Use the above formats, it will be taken care

Please use

 CellType.equals("Hamster");

If you want to ignore case then use,

 CellType.equalsIgnoreCase("Hamster");

== is the identity comparison operator (same object). You should use equals() when you want to compare equivalence.
