How-to articles, tricks, and solutions about GENERICS

To create an instance of a generic type in Java, you can use the newInstance() method of the Class class, along with the Type and TypeVariable classes.

If you want to get the generic type of a class at runtime, you can use the Type class in the System namespace.

An unchecked cast warning in Java occurs when the compiler cannot verify that a cast is safe at compile time.

To get a class instance of a generic type T, you can use the new operator and specify the type argument when creating an instance of the class. Here's an example:

To make the return type of a method generic in Java, you can use a type parameter. A type parameter is a placeholder for a specific type that will be specified when the method is called.

In Java, it is not possible to create a generic array directly. However, you can create an array of a specific type and then cast it to a generic type.

In Java, the Class<T> class represents the class or interface type of a class at runtime.

The javac compiler may issue the "uses unchecked or unsafe operations" warning if your code uses operations that may result in an Unchecked warning at runtime.

@SuppressWarnings("unchecked") is an annotation in Java that tells the compiler to suppress specific warnings that are generated during the compilation of the code.
