We Are Going To Discuss About Java 8 lambda get and remove element from list. So lets Start this Java Article.
Java 8 lambda get and remove element from list
- Java 8 lambda get and remove element from list
To Remove element from the list
objectA.removeIf(x -> conditions);
eg:objectA.removeIf(x -> blockedWorkerIds.contains(x));
- Java 8 lambda get and remove element from list
To Remove element from the list
objectA.removeIf(x -> conditions);
eg:objectA.removeIf(x -> blockedWorkerIds.contains(x));
Solution 1
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

Solution 2
Use can use filter of Java 8, and create another list if you don’t want to change the old list:
List<ProducerDTO> result = producersProcedureActive
.stream()
.filter(producer -> producer.getPod().equals(pod))
.collect(Collectors.toList());

Solution 3
The below logic is the solution without modifying the original list
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");
List<String> str3 = str1.stream()
.filter(item -> !str2.contains(item))
.collect(Collectors.toList());
str1 // ["A", "B", "C", "D"]
str2 // ["D", "E"]
str3 // ["A", "B", "C"]

Solution 4
Although the thread is quite old, still thought to provide solution – using Java8
.
Make the use of removeIf
function. Time complexity is O(n)
producersProcedureActive.removeIf(producer -> producer.getPod().equals(pod));
API reference: removeIf docs
Assumption: producersProcedureActive
is a List
NOTE: With this approach you won’t be able to get the hold of the deleted item.
