This is convenient but can also be dangerous due to loss of data. Code: Private i As Int = 50000 Private s As Short = 0 s = i Log(s) '-15536 In Java, those conversions that may lose data are called narrowing and must be explicitly demanded by the programmer using a cast Code: int i = 50000; short s = 0; //s = i; //error when writing code s = (short) i; //explicit casting System.out.println(s); //-15536 Would it be possible to implement that the IDE issues a warning when narrowing takes place?
