this as an example to describe the type checking and conversion of swift classes, including the IS operator, as operator, and any and anyobject types.First, using the IS operatorThe IS operator can determine whether an instance is a type of a class. If the instance is a target type, the result returns True, otherwise false.Let's look at an example:Let Student1 = Student (name: "Tom", Age:18, School: "Tsinghua University") ①let Student2 = Student (name: "Ben

As for the theoretical aspects of the said, you can view the API, now mainly give a few examples to illustrate the difference between:
Example one:
String sample1= "Ben Ben"; With a 8-space interval between Ben.
string[] split1 = Sample1.split (""); Isolate by a space
Final listFinal StringTokenizer tokens = new StringTokenizer (Sample1, "");
Results: Split1
The instanceof operator can be used to determine whether a constructor's prototype property exists on another prototype chain to detect an object.
Example one: Universal usage
A instanceof B: detects whether the B.prototype exists on the prototype chain of parameter A.
Function Ben () {
}
var ben = new Ben ();
