What is the difference between an implicit conversion and an explicit conversion?
1. Explicit conversions require a cast operator whereas an implicit conversion is done automatically. <br> 2. Explicit conversion can lead to data loss whereas with implicit conversions there is no data loss. <br> What type of data type conversion happens when the compiler encounters the following code?ChildClass CC = new ChildClass(); <br> ParentClass PC = new ParentClass(); <br><br> Implicit Conversion. For reference types, an implicit conversion always exists from a class to any one of its direct or indirect base classes or interfaces. No special syntax is necessary because a derived class always contains all the members of a base class. <br><br> Will the following code compile? <br> double d = 9999.11;<br> int i = d;<br><br> No, the above code will not compile. Double is a larger data type than an integer. An implicit conversion is not done automatically bcos there is a data loss. Hence we have to use explicit conversion as shown below. <br><br> double d = 9999.11;<br> int i = (int)d; //Cast double to int.<br>
