The use of the Java instanceof method

The instanceof operator in Java is used to indicate at run time whether an object is an instance of a particular class. Instanceof Indicates whether this object is an instance of this particular class or its subclasses by returning a Boolean value.
Usage:
Result = Object Instanceof class
Parameters:
Result: Boolean type.
Object: Required option. An arbitrary object expression.
Class: Required option. Any of the defined object classes.
Description
If object is an instance of class, the instanceof operator returns TRUE. Returns False if object is not an instance of the specified class, or if object is null.

The //instanceof method works the same way as the following Object.getclass (). GetName ().   //if (object instanceof Apple) {System.out.println (Object.getclass (). GetName ()); if(Object.getclass (). GetName (). Equals ("First".

(Perhaps because the external method is applied to many different classes * and you don't want to repeat the code.) For example, I can expand people not only to eat apples but also to eat oranges. We can plant an orange first. */classPeeler {StaticApple Peel (Apple apple) {System.out.println ("Plant a little apple:" +Apple); //.. remove Peel    returnApple//Peeled  }  StaticOrange peel (orange orange) {System.out.println ("Plant a small orange:" +Orange); returnOrange; }}classApple {Apple getpeeled () {returnPeeler.peel ( This); }}classOrange {Orange getpeeled () {returnPeeler.peel ( This); }} Public classPassingthis { Public Static voidMain (string[] args) {NewPerson ().
