public static void main(String[] args) { String[] keyArrayStr = new String[]{"123","ewe","323","093"}; Map<String,String> removeMap = new HashMap<String,String>(); removeMap.put("123", "1"); removeMap.put("ewe", "1"); removeMap.put("323", "1"); removeMap.put("093", "1"); // 注意这里:单纯的使用 Arrays.asList 把数组转换为集合后,使用 .add() .remove() 会报 java.lang.UnsupportedOperationException 错误 // 原因:Arrays.asList 转换的ArrayList 是内部类,并不是 java.util.ArrayList,内部类下没有 add、remove 方法导致的。 // 解决方案: new ArrayList(Arrays.asList()); List<String> tempList = new ArrayList(Arrays.asList(keyArrayStr)); for (int i = 0; i < tempList.size(); i++) { if (removeMap.containsKey(tempList.get(i))) { tempList.remove(i); i--; } } keyArrayStr = tempList.toArray(new String[tempList.size()]); }
