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

// 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)
