java.util.regex.Pattern

[Dave Jones]

Hi
I want to check my input string that it contains only the characters:
a-z, A-Z , 0-9, [,],{,},/,,, ,_,

I was told I can use a Pattern , but when looking it up, I didn't find what I need, can anyone shed some light here ?
Thanks
p.s - I know I could do it the hard way by running a char char check, but I want to avoid that way

String pattern = "^[a-zA-Z0-9\\[\\]{}/, _]+$";
System.out.println("c D 1 [] {} / , _".matches(pattern)); // true
System.out.println(".?!@#$%^&*()".matches(pattern));      // false
System.out.println("foo!bar".matches(pattern));           // false

/* Edit */
I really need another cup of coffee...

Are you saying you didn't find the Pattern javadoc? Try here.

For a little sample code that uses Pattern, look this discussion.

Does that clear it up?
