The correct answer is **interface**.

### Explanation
In Java, interfaces are a fundamental concept used to define a contract or a set of methods that a class must implement. The keyword `interface` is specifically reserved for this purpose in the Java programming language. By defining an interface, you can specify methods that must be implemented by any class that chooses to "implement" the interface.

This promotes abstraction and allows for multiple classes to implement the same interface in different ways. The use of interfaces supports polymorphism in Java, allowing for the creation of methods that can operate on objects of classes that implement the same interface, regardless of their actual class types.

The other options provided—`intf`, `Int`, and `float`—are not keywords for defining interfaces in Java.

Thus, for defining interfaces in Java, **interface** is the appropriate keyword to use.
