第一种情况： Comparator cmp = Collator.getInstance(java.util.Locale.CHINA); String[] arr = { "张三", "李四", "王五", "刘六" }; Arrays.sort(arr, cmp); for (int i = 0; i < arr.length; i ) System.out.println(arr[i]); 第二种情况： //ComparableBean.java import java.text.CollationKey; import java.text.Collator; import java.text.RuleBasedCollator; import java.util.Comparator; public class ComparableBean{ private String name; public ComparableBean(String name) { this.name = name; } public String getName() { return name; } public void setName(String name) { this.name = name; } } class ComparableBeanComparator implements Comparator//<ComparableBean> { RuleBasedCollator collator; // you can set your rules for the instance "collator" public ComparableBeanComparator() { collator = (RuleBasedCollator)Collator.getInstance(java.util.Locale.CHINA);// try testing various locales } public int compare(Object obj1, Object obj2) { String tempname1 = ((ComparableBean) obj1).getName(); String tempname2 = ((ComparableBean) obj2).getName(); CollationKey c1 = collator.getCollationKey(tempname1); CollationKey c2 = collator.getCollationKey(tempname2); // return collator.compare(((CollationKey) c1).getSourceString(), // ((CollationKey) c2).getSourceString()); return collator.compare(((CollationKey) c2).getSourceString(), ((CollationKey) c1).getSourceString()); } // public int compare(ComparableBean obj1, ComparableBean obj2) { // String tempname1 = obj1.getName(); // String tempname2 = obj2.getName(); // // CollationKey c1 = collator.getCollationKey(tempname1); // CollationKey c2 = collator.getCollationKey(tempname2); // return collator.compare(((CollationKey) c1).getSourceString(), // ((CollationKey) c2).getSourceString()); // } } //the end of ComparableBean.java 测试代码： ComparableBean[] nameContent = { new ComparableBean("一切从实际出发"), new ComparableBean("立于不败之地"), new ComparableBean("多项式"), new ComparableBean("贯彻落实"), new ComparableBean("密切联系群众"), new ComparableBean("四项基本原则"), new ComparableBean("咬牙切齿"), new ComparableBean("恭恭敬敬"), new ComparableBean("民警"), new ComparableBean("经营承包责任制") }; Arrays.sort(nameContent,new ComparableBeanComparator()); for (int i = 0; i < nameContent.length; i ) { System.out.println(nameContent[i].getName()); }
