String Manipulation

[TheVooDooChild]

I have an alpha-numeric string. If the 1st position is non-numeric, I
need to remove it. For some reason this is causing me difficulty. Can
someone show me a way to do this? Example: "R123456789" I want
"123456789"

Thanks.

String s = "R123456789" ;

//get first char
char c = s.charAt(0) ;

//is it non-numeric?
if(!Character.isDigit(c)){
//remove it
s = s.substring(1,s.length());
}

Thank you!

String s = "R123456789" ;

//get first char
char c = s.charAt(0) ;

//is it non-numeric?
if(!Character.isDigit(c)){
//remove it
s = s.substring(1,s.length());
}

you can use "s = s.substring(1);"
instead of specifying the length explicitly
