Note that by castingtarget.getElementType()to aRefType, we eliminate all cases where the element type is a primitive type, that is,targetis an array of primitive type: the problem we are looking for cannot arise in that case. Unlike in Java, a cast in QL never fails: if an expression...
It’s probably good to begin by stating that since Groovy is based on Java, it has all of Java’s String capabilities like concatenation, the String API, and the inherent benefits of the String constant pool because of that. Let’s first see how Groovy extends some of these basics. ...

You can convert between data types using type conversion functions or casting. For example, in Python, you can use int () to convert a value to an integer or str () to convert it to a string. What is the difference between implicit and explicit type conversion?
To cast an object to another object, place the type of object you are casting to in parentheses immediately before the object you are casting. Object a = new Object; String b = (String)a; // Cast to String Illegitimate narrowing results in a ClassCastException. Narrowing may result in a...
For example, int x = 1.0 would be illegal because the data type of x is int. You cannot assign a double value (1.0) to an int variable without using type casting. Type casting is introduced in §2.8, "Numeric Type Conversions."2.5.1. Declaring and Initializing Variables in One Step...
Sometimes you'll have a value in your Java program that isn't the right type for what you need. It might be the wrong class or the wrong data type, such as a float when you need an int. You use casting to convert a value from one type to another. Casting is the process of prod...

Upcasting is a form of casting where you cast up the inheritance hierarchy from a subtype to a supertype. No cast operator is involved because the subtype is a specialization of the supertype. For example, Shape s = new Circle(); upcasts from Circle to Shape. This makes sense because a ...
