For example, in our case those four rows will get dense rank 1, 1, 1 and 2. So there is no gap between ranks. If you look closely, it's actually the same as using ROW_NUMBER with unique rows or using distinct with ROW_NUMBER. ...
and StringstrLiteral="Java"; Both expressions give you a String object, but there is a subtle difference between them. When you create a String object using thenew()operator, it always creates a new object inheap memory. On the other hand, if you create an object using String literal syn...
