Java ListIterator Usage filterStringList(final String prefix, final String infix, final String suffix, final List list)

Declaration

public static List filterStringList(final String prefix, final String infix, final String suffix,
        final List list) 

Method Source Code

//package com.java2s;
import java.util.ArrayList;
import java.util.List;
import java.util.ListIterator;

public class Main {
    /**/*from ww  w . j  a  v a  2s  .c o m*/
     * Filters the given list of strings, taking all elements that start with the given prefix, contain the given infix
     * and end with the given suffix and returning them as a new list. The given list will not be modified. All three
     * search arguments are optional.
     * 
     * @param prefix
     *          Prefix to look for. If null, this method will not filter by prefixes.
     * @param infix
     *          Infix to look for. If null, this method will not filter by infixes.
     * @param suffix
     *          Suffix to look for. If null, this method will not filter by suffixes.
     * @param list
     *          List that is to be filtered. If empty or null, an empty list will be returned.
     * @return filtered List<String>
