一、集合操作
1、数组转集合
List<String> vinParamList = new ArrayList<>();
Collections.addAll(vinParamList,vins);
2、求两个集合的差
List<String> initNumA = initNumA();
List<String> initNumb = initNumB();
List<String> diffList = initNumA.stream().filter(item -> !initNumb.contains(item)).collect(toList());
A 集合减去B
3、集合拆分 -guava
import com.google.common.collect.Lists;
List<List<String>> partition = Lists.partition(initNumA(), NUMBER_TWO);
