Type casting is when you assign a value of one primitive data type to another type. In Java, there are two types of casting:Widening Casting (automatically)- converting a smaller type to a larger type size. byte -> short -> char -> int -> long -> float -> double. What means type...

On the other hand, the conversion in the opposite direction is known as explicit conversion. It needs a cast operator to convert higher data type into a smaller data type. This type of conversion is not type-safe and may result in loss of data. Data Type Casting in C# In this tutorial,...

This program is using Oracle OJDBC specific classes and won’t work with other database. We are setting OUT parameter type asOracleTypes.CURSORand then casting it toResultSetobject. Other part of the code is simple JDBC programming. When we execute above CallableStatement example program, we get...

String str=(String) obj;//type casting leading to ClassCastException at runtime } Above code compiles fine but throws ClassCastException at runtime because we are trying to cast Object in the list to String whereas one of the element is of type Integer. After Java 5, we use collection ...

Essentially this is talking about the practical use of inheritance/object hierarchy. He is using Object because in Java everything (thats not a primitive type) is a Object at its root. For example, suppose we have an application for tracking automobiles. We could have a Car class, a...
