How to Use String Patterns?

Question

Hai all,
I need help, In my project i am using String patterns.
i need to search a string which contains special characters.
Ex:
1.Abstract{meaning}
I have to search Abstract in this case.
Another case is:
2.Moon
in this i Have to search Moon and
so on.
For this Source Code I had written is:
string input = args[0];
String pattern = "[0-9].*+\\{*\\}";
String pattern1 = "[0-9].*";
string line = "1.Abstract{meaning}";
string line1 = "1.Moon";
if( (Pattern.matches(pattern, line))||(Pattern.matches(pattern1, line1)) )
Pattern p = pattern.compile("\\.");
Pattern p1 = pattern.compile("\\{");
String[] tokens = p.split();
String[] tokens1 = p1.split();
for(int i = 0; i < tokens.length ; i++)
for(int j = 0; j < tokens1.length ; j++)
if((tokens.equals(input))||(tokens[j].equals(input)))
System.out.println(tokens[i]);
System.out.println(tokens[j]);
in this code it matching the 2nd case. it is not matchinf the 1st case.
please help me.
Thanks

look up for "Using formatters" in the FB help.
Essentially you'll instantiate a format, NumberFormatter for
numbers for example, and set it's properties like e.g. showing a
thousand separator and then one some event of the TextInput --
valueCommit for example -- you'll do something like:
ti.text = nf.format(ti.text)
this is would also give you opportunity to validate user
input using the same formatter and valid event.
