Question

I am actually writing a program to generate some truely random numbers. So, i am trying to write an algorithm to calculate from various factor.And i want to define my own encoding, so that when it is converted, it can only be strings of certain characters.

for example, the user wants only small letters, so i want something like this:

char[] result;
String result = new String(result,"MY OWN ENCODING")

Is there a way ?

Thanks alot !

You probably want to create a converter class:

public class Converter {

  private String charset;
  public Converter(String charset) {this.charset = charset;}

  public char[] convert(char[] input) {

    char[] result = new char[input.length];
    // do your own magic
    return result;
  }
}

Once the magic converter logic is implemented and in place:

Converter converter = new Converter("abcdefghijklmnopqrstuvwxyz");
char[] result = converter.convert(myCharArray);
