自定义枚举类

import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;
import java.util.Arrays;
@Getter
@NoArgsConstructor
@AllArgsConstructor
public enum ProContant {QCC("QCC",1),FQCC("FQCC",2),HELIHUA("合理化",3),TOPN("TOPN",4),HEIDAI("黑带",5),LVDAI("绿带",6);private String key;private Integer index;public static ProContant getProContant(String str) {return Arrays.stream(ProContant.values()).filter(proContant -> str.equals(proContant.getKey())).findFirst().orElse(null);}
}

测试

import java.util.Arrays;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;public class Test {public static void main(String[] args) {List<String> list = Arrays.asList("绿带", "合理化", "黑带", "QCC", "FQCC", "TOPN");System.out.println("原集合："+list);Collections.sort(list, new Comparator<String>() {@Overridepublic int compare(String o1, String o2) {return ProContant.getProContant(o1).getIndex() - ProContant.getProContant(o2).getIndex();}});System.out.println("排序后的集合"+list);}
}

简写方式

import java.util.Arrays;
import java.util.Comparator;
import java.util.List;
public class Test {public static void main(String[] args) {List<String> list = Arrays.asList("绿带", "合理化", "黑带", "QCC", "FQCC", "TOPN");System.out.println("原集合："+list);list.sort(Comparator.comparingInt(o -> ProContant.getProContant(o).getIndex()));System.out.println("排序后的集合："+list);}
}

运行结果：
原集合：[绿带, 合理化, 黑带, QCC, FQCC, TOPN]
排序后的集合：[QCC, FQCC, 合理化, TOPN, 黑带, 绿带]
