Java instance of

In Java, the instanceof operator is used to determine if an object is an instance of a specific class or interface. It has the following syntax:

object instanceof Class

For example:

String str = "Hello";
boolean isString = str instanceof String;  // isString is true

Object obj = new Object();
boolean isObject = obj instanceof String;  // isObject is false

The instanceof operator returns true if the object is an instance of the specified class or interface, or if the object is an instance of a subclass or subinterface of the specified class or interface. It returns false if the object is not an instance of the specified class or interface.

The instanceof operator is often used in Java to check the type of an object before casting it to a specific type. For example:

Object obj = getObject();
if (obj instanceof String) {
  String str = (String) obj;
  // do something with str
}

For more information on the instanceof operator in Java, you can refer to the Java documentation.
