How to use instance of dynamically in java?

I have a string variable which stores the name of a class (e.g. String,Integer etc)

String type = "String";

I have an object which i need to check if it is an instance of the class whose name is stored in the string variable. How do I check it ?

if (object instanceof type){
   // Do something here
}

However, the above logic doesn't work as the variable type is not recognized as a class. So, how do I dynamically check if an object is an instance of 'type'.

If you have the fully qualified name of the class, you can use Class.forName("java.lang.String").isAssignableFrom(type).

If you don't have qualified names, you'll have to code out a mapping, something like this:

switch (typeName) {
  case "String": return type instanceof String;
  case "Integer": return type instanceof Integer;
  // et cetera
}
