Question

If blue j is a case sensitive then how can we write d or D ,forF To specify that a value is double or Float

Answer 1

I think the value is float

Answer 2

We can use capital/small f/d because they are the type indicates for numeric literals, float or double, in Java and using either conveys the same message to the compiler - that though the literal can fit in another type, it gotta be be in this , explicitly(it's kinda like casting). The java language has registered it's meaning for the same, no matter what the case is(NOT JUST IN BLUEJ, IT'S THE PROTOCOL FOR JAVA LANGUAGE).

SO, YOU CAN USE "F/D/L" OR "f/d/l" (not recommended tho)
