Comparing something something to a data type (like char, string, etc.)

I started programming Java 3 Weeks ago, because we started it in School. Now I got a Question, I hope, you can help me!

I want to compare a Variable (in my Case a Integer) to a Data Type:

int a;
(...)
if (a != int) {
System.out.println ("I can only work with Integers")
}
else { }

So everytime, if I type into the Scanner a Char or Double or something different than an Integer, the Program will give a different Output or an Error.

Can you help me, how to compare the Both Types?

Thank you for your answers!

To check a type of variable in Java you can use the instanceof operator.

Example :

if(a instanceof String) {
System.out.println("This is a String!");
}
