Currently i have a method calling String.format() in Java 5 and it's working perfectly
String.format("%02x", octet) //octet is a int type
However due to some issue we need to deploy this code in a JDK 1.4 environment, and String.format doesn't exists in 1.4.
Anyone knows any alternative way to perform this function?

In java, String format() method returns a formatted string using the given locale, specified format string, and arguments. We can concatenate the strings using this method and at the same time, we can format the output concatenated string. Syntax: There is two types of string format() method.
"%5d" Format a string with the required number of integers and also pad with spaces to the left side if integers are not adequate. "%05d" Format a string with the required number of integers and also pad with zeroes to the left if integers are not adequate.
%s refers to a string data type, %f refers to a float data type, and %d refers to a double data type.
In your example, it is a placeholder character. It means when % is encountered, the next character determines how to interpret the argument and insert it into the printed result. %s means interpret as string, %d is for digit, %x is digit in hexadecimal, %f is for float, etc....
You could use something like this snippet:
String hexString = Integer.toHexString(octet);
if (hexString.length() < 2) {
hexString = "0" + hexString;
}
You need to use Integer.toHexString(int) and pad the text yourself.
