Sometimes you'll have a value in your Java program that isn't the right type for what you need. It might be the wrong class or the wrong data type, such as a float when you need an int. You use casting to convert a value from one type to another. Casting is the process of prod...
Notice that when Java detects that type conversion may result in data loss (bigger data type to smaller one), then gives atype-mismatch errorand explicitly asks fortype casting(e.g. ‘int’ to ‘short’ assignment). It helps in detecting and resolving accidental data loss assignments. 2.2. ...
An integer literal of type long always ends with ‘L’ (or lowercase ‘l’). longnum1=0L;longnum2=401L;longmum3=-3556L; Even if the value stored in alongvariable is well within the range of theintdata type, theassignment from long to int is not allowedwithout explicittype casting,...

use the FCL type names and completely avoid the primitive type names. the C# compiler supports patterns related to casting, literals, and operators. 1.casting C# allows implicit casts if the conversion is “safe”(no loss of data is possible);But C# requires explicit casts if the conversion ...
When using thejavaTypecustomization element you must specify methods for converting the XML representation of the primitive type to and from the target Java class. Some mappings have default conversion methods. For instances where there are no default mappings, Apache CXF ...

On the one hand you can already quite easily shoot yourself in the foot with something like: JValue::from('💣' as jchar) and I guess if a TryFrom implementation existed that could also act as a clue that the conversion will be lossy in case someone is not aware that a Java char ...
Note you need two additional pairs of () because the precedence of the dot operator is higher than casting. Note that procedure is called boxing conversion (some people call it autoboxing). And that is as near as you can get to what I think you were suggesting. Try it and see what ...
