Unlike C, local variables cannot WebWhen converting one data type to another, the destination type should be greater than the source data type. ,. If we want to assign a value of a larger data type to a smaller data type we perform explicit type casting or narrowing. For small values, casting is enough: long l = 42; int i = (int) l; However, a long can hold more information than an int, so it's not possible to perfectly convert from long to int, in the general case.If the long holds a number less than or equal to Integer.MAX_VALUE you can convert it by casting without losing any information.. For example, the following sample code: Now I don't quite use web but I do have a moodle platform that would work better (due to scorm) with html.
