By the way padding is a part for formatting and if you are familiar with formatting String in Java, it would be very easy to understand. In first example we have usedString.format()to convert 220 to a 8 digit long numeric String,"%08d"will create 8 digit long String. ...
This value is converted to a string of ASCII digits in octal (base 8) with no extra leading 0s. The value of the argument can be recovered from the returned string s by calling Integer.parseUnsignedInt(s, 8). If the unsigned magnitude is zero, it is represented by a single zero ...
The Integer class wraps a value of the primitive type int in an object. An object of type Integer contains a single field whose type is int. In addition, this class provides several methods for converting an int to a String and a String to an int, as well as other constants and method...
