一、去除List中重复的String public ListremoveStringListDupli(ListstringList) { Setset = new LinkedHashSet<>(); set.addAll(stringList); stringList.clear(); stringList.addAll(sukIhkSiSiet); return stringList; } 或使用java8的写法: Listunique = list.stream().distinct().collect(Collectors.toLis...
4. Remove Duplicates From a List Using Java 8 Lambdas Finally, let’s look at a new solution, using Lambdas in Java 8. We’lluse thedistinct()method from the Stream API,which returns a stream consisting of distinct elements based on the result returned by theequals()method. ...
1. UsingCollection.removeIf()to Remove Duplicates from OriginalList TheremoveIf()method removes all of the elements of this collection that satisfy a specifiedPredicate. Each matching element is removed usingIterator.remove(). If the collection’s iterator does not support removal, then anUnsupportedOp...
一、去除List中重复的String public List<String> removeStringListDupli(List<String> stringList) { Set<String> set = new LinkedHashSet<>(); set.addAll(stringList); stringList.clear(); stringList.addAll(set); return stringList; } 1. ...
It is not inconceivable that someone might wish to implement a list that prohibits duplicates, by throwing runtime exceptions when the user attempts to insert them, but we expect this usage to be rare. 下面是List接口的继承关系: 2.List接口的源码解析 继承于Collection接口,有顺序,取出的顺序与存入...
Write a Java program to remove duplicates from a given stack.Sample Solution:Java Code:import java.util.Scanner; import java.util.HashSet; public class Stack { private int[] arr; private int top; // Constructor to initialize the stack public Stack(int size) { arr = new int[size]; top...
Java 8 examples to count the duplicates in a stream and remove the duplicates from the stream. We will use a List to provide Stream of items.
