Ascii to hex converter

[Ghaith Shamayleh]

I would like if there is a function in java that can be used to covert a string of ascii to a string of hex, or should i write a method to write this, can anyway help

This one does it one character at a time; I'm actually cramming unicode into byte, but if you have ASCII (in 7 or 8 bits), it will cast to byte as well.

public class HexBytes
{
  public static void main(String args[])
  {
    String testString = "abcdefghijklmnopqrstuvwxyz";
    for (int i=0; i<testString.length(); i++)
    {
      System.out.println(String.format("%x", (byte)(testString.charAt(i))));
    }
  }
}

Look up details for formatting string output under java.util.Formatter

this will take a string of hex and convert it or a string of ascii and covert it

[Campbell Ritchie]

What is a String of hex? Do you mean a String which only contains the characters 0-9 a-f and A-F? Your last comment appears to want the opposite of what the thread title says you want.
