Java.lang.Integer cannot is cast to java.lang.String

The reason for the error is type conversion!
Says the integer type cannot be converted to a string type.

Workaround:

Modify the (String) cast type in the error to object.tostring ()

The ToString method is a public method of the Java.lang.Object object. Any object in Java Inherits object objects, so it is generally possible for any object to call the ToString method. When this method is used, often derived classes override the ToString () method in object.
