Instantiating a generic class in Java [duplicate]

Answer 1

Use The Constructor.newInstance method. The Class.newInstance method has been deprecated since Java 9 to enhance compiler recognition of instantiation exceptions.

public class Foo {   
    public Foo()
    {
        Class newT = null; 
        instantiateNew(newT);
    }

    T instantiateNew(Class clsT)
    {
        T newT;
        try {
            newT = (T) clsT.getDeclaredConstructor().newInstance();
        } catch (InstantiationException | IllegalAccessException | IllegalArgumentException
            | InvocationTargetException | NoSuchMethodException | SecurityException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            return null;
        }
        return newT;
    }
}
