Various digital types are converted into string type: string s = string.valueof (value); // where Value is any number of digital types. String type conversion into various digital types: string s = "169"; byte b = byte.parsebyte (s); short t = short.parseshort (s); int i = integer.parseint (s); long l = Long.Parselong (s); float f = float.parsefloat (s); double d = double.parsedouble (s); transition between digital types and digital objects: BYTE B = 169; Byte Bo = New Byte (B ); b = bo.bytevalue (); short t = 169; short to = new short (t); t = to.shortvalue (); int i = 169; integer = new integer (i); i = IO. INTVALUE (); long L = 169; long lo = new long (l); l = l = 169f; float f = new float (f = fo.floatvalue (); Double D = 169f; double dobj = new double (d); d = dobj.doublevalue ();
