Which is a valid keyword in java?

interface

string

Float

unsigned

Answer : Option A

Explanation :

interface is a valid keyword.

Option B is wrong because although "String" is a class type in Java, "string" is not a keyword.

Option D is wrong because "unsigned" is a keyword in C/C++ but not in Java.
