How can I achieve this?

public class GenericClass
{
    public Type getMyType()
    {
        //How do I return the type of T?
    }
}

    One simple solution for this cab be like below

    public class GenericDemo{
        private T type;
    
        GenericDemo(T t)
        {
            this.type = t;
        }
    
        public String getType()
        {
            return this.type.getClass().getName();
        }
    
        public static void main(String[] args)
        {
            GenericDemo obj = new  GenericDemo(5);
            System.out.println("Type: "+ obj.getType());
        }
    }
