Save an integer in two digit format in a variable in Java

Question

How can I store an integer in two digit format in Java? Like can I set

int a=01;

and print it as 01? Also, not only printing,

Answer 1

I think this is what you're looking for:

int a = 1;
DecimalFormat formatter = new DecimalFormat("00");
String aFormatted = formatter.format(a);

System.out.println(aFormatted);

Or, more briefly:

int a = 1;
System.out.println(new DecimalFormat("00").format(a));

An int just stores a quantity, and 01 and 1 represent the same quantity so they're stored the same way.

DecimalFormat builds a String that represents the quantity in a particular format.

Answer 2

This is not possible, because an integer is an integer. But you can format the Integer, if you want (DecimalFormat).

Answer 3

// below, %02d says to java that I want my integer to be formatted as a 2 digit representation
String temp = String.format("%02d", yourIntValue);
// and if you want to do the reverse
int i = Integer.parse(temp);

// 2 -> 02 (for example)

Answer 4

look at the below format its work above format can work for me

System.out.printf("%02d", myNumber)
