Java 8 lambda 从列表中获取和删除元素
Given a list of elements, I want to get the element with a given property and remove it from the list. The best solution I found is:
ProducerDTO p = producersProcedureActive
.stream()
.filter(producer -> producer.getPod().equals(pod))
.findFirst()
.get();
producersProcedureActive.remove(p);
Is it possible to combine get and remove in a lambda expression?
解决方案To Remove element from the list
objectA.removeIf(x -> conditions);
eg:
objectA.removeIf(x -> blockedWorkerIds.contains(x));
List<String> str1 = new ArrayList<String>();
str1.add("A");
str1.add("B");
str1.add("C");
str1.add("D");
List<String> str2 = new ArrayList<String>();
str2.add("D");
str2.add("E");
str1.removeIf(x -> str2.contains(x));
str1.forEach(System.out::println);
OUTPUT: A B C
