按长度对字符串列表进行排序

使用自定义比较器：

public class MyComparator implements java.util.Comparator<String> {    private int referenceLength;    public MyComparator(String reference) {        super();        this.referenceLength = reference.length();    }    public int compare(String s1, String s2) {        int dist1 = Math.abs(s1.length() - referenceLength);        int dist2 = Math.abs(s2.length() - referenceLength);        return dist1 - dist2;    }}

然后使用对列表进行排序

java.util.Collections.sort(List, Comparator)
