Casting a char element so it can be used in an int method?

Question

I have this code,

public int deleteSubString(String delSubString) 
{
    int len = delSubString.length();
    char []temp = delSubString.toCharArray();
    char first = 0;
    temp[0] = first ;
    System.out.println(first);
    System.out.println(len);
    return deleteSubString(first,len);
}

Inorder for it to work correctly the overloaded deleteSubString method in the return statment needs to take two integers to return deleteSubString( int first, int len). I can't seem to cast to an integer. Is it possible to get an integer out of the temp char array.

your question is unclear. What is the output that you expect and what is this program for..? — Thirumalai Parthasarathi, Sep 14 '13 at 11:10

Try this:

return deleteSubString(Character.getNumericValue(first), len);
