This section describes type casting supported in Java: up casting (widening reference conversion) and down casting (narrowing reference conversion). Cast operation can be written explicitly with the cast operator (T), or implicitly with no operator.©...
V548. TYPE X[][] is not equivalent to TYPE **X. Consider inspecting type casting. V549. The 'first' argument of 'Foo' function is equal to the 'second' argument. V550. Suspicious precise comparison. Consider using a comparison with defined precision: fabs(A - B) < Epsilon or fabs(...
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,...
The conversion of adata typewhich is carried out automatically by the compiler without programmer intervention is called the implicit type conversion. When two variables of different data types are involved in the same expression, theJavacompiler uses built-in library functions to trans- form the var...

There are two ways of casting a primitive data type into another. Case 2 as mentioned by you uses Explicit casting and is prone to data loss. Implicit casting as in Case 1, gives compilation error as there is a possible loss of imformation. char is 'unsigned' while byte is 'signed' ...

In Clu it is called any; in Modula-2, address; in Modula-3, refany; in Java, Object; in C#, object. Arbitrary l-values can be assigned into an object of universal reference type, with no concern about type safety: because the type of the object referred to by a universal reference...
