I want to create a subarray from an array based on pattern match.

i want to create an array which should contain only those element which starts from 1. i.e

 {"123","134"}

Kindly help.

Answer 1

the fastest solution i can think.

matchArray(regex,array)
    {
    ArrayList list=new ArrayList();
    for(String o in array){
    if(o.match(regex)){
    list.add(o);
    }
    }
    return list.toArray();
    }
