Java 字符串数字混合list集合排序排序后样式：关键代码//sort listListKpiView kpiViews = (ListKpiView) query.execute();ComparatorKpiViewName comparatorKpiViewName = new ComparatorKpiViewName();Collections.sort(kpiViews,comparatorKpiViewName);import java.util.Comparator;import com.kpi.entity.KpiView;publicclass ComparatorKpiViewName implementsComparator {@Overridepublicint compare(Object o1, Object o2) {KpiView kpiView1 = (KpiView) o1; KpiView kpiView2 = (KpiView) o2;String s1=kpiView1.getKpiViewName().toLowerCase();String s2=kpiView2.getKpiViewName().toLowerCase();if (s1.charAt(0) s2.charAt(0)) { return 1; } elseif (s1.charAt(0) s2.charAt(0)) { return -1; } else { //The alphanumeric section String alphabet1 = s1.replaceAll(\\d+$, ); String alphabet2 = s2.replaceAll(\\d+$, );// If you dont want to case-sensitive, or compareToint cmpAlphabet = pareToIgnoreCase(alphabet2);if (cmpAlphabet != 0) {return cmpAlphabet; }//Digital section String numeric1 = s1.replaceAll(^[a-zA-Z]+, ); String numeric2 = s2.replaceAll(^[a-zA-Z]+, );if (.equals(numeric1)) {/* Even if the numeric2 is the empty string also does not matter, of course, if the comparison is not String ( or other immutable objects ) is another matter*/return -1; }if (.equals(numeric2)) {return 1; }int result=Integer.parseInt(numeric1) - Integer.parseInt(numeric2);return result; } } }
