How do I convert one object to another in TypeScript?
JavaScript has no concept of type conversion because variables are dynamically typed. However, every variable in TypeScript has a type. Type conversions allow you to convert a variable from one type to another. In TypeScript, you can use the as keyword or the <> operator for type conversion.

How do you convert an object to another type in Java?
The first step in converting one object to another is to define a function. Mentioned above, a function will accept a type of GoogleLocation and return an instance of MyLocation. Inside this method, we will create a new MyLocation object and set the values passed in from GoogleGeoLocation.
What is the use of object type conversion in Java?
Type Casting is a Java feature whereby the form or type of a variable or object is converted to some other type or object, and the process of converting from one type to another is called Type Casting. Before we dive into the typecasting process, let’s understand data types in Java.
Can a Java object be converted to another Java object?
The java object type that is typecast by an object reference can be converted to another object reference. The conversion can be to its own class type or to one of its subclass or superclass types or interfaces. There are compile time rules and runtime rules for converting in Java.
When does a ClassCastException occur during object conversion?
Here is an example showing when a ClassCastException can occur during object conversion. In general, an implicit conversion is performed when an object reference (conversion) is assigned to: * A reference variable whose type is the same as the class from which the object is instantiated. An Object as Object is a superclass of every Class.
What are the names of the conversion operators in Java?
In order to control this type of conversions between classes, we have four specific casting operators: dynamic_cast, reinterpret_cast, static_cast and const_cast. Its format is to follow the new type enclosed in angle brackets ( <>) and immediately after, the expression to convert between parentheses.
What happens when you cast between reference types?
A conversion operation between reference types does not change the runtime type of the underlying object; it only changes the type of the value that is being used as a reference to that object. For more information, see Polymorphism.
