A Simple Example of HashSet in Java Let’s see a simple HashSet example, where we are adding few string elements to HashSet and then iterating the HashSet to print the elements. importjava.util.HashSet;publicclassJavaExample{publicstaticvoidmain(Stringargs[]){// HashSet declarationHashSet<...
In Step 1, we have created two objects of LinkedHashSet collection, we have defined these objects to store value of String type and Integer type. In Step 2, we have used add method to store values in the data structures that we have created in step 1. In Step 3, we have printed va...
HashSetdoesn’t maintain any kind of order of its elements. TreeSetsorts the elements in ascending order. LinkedHashSetmaintains the insertion order. Elements gets sorted in the same sequence in which they have been added to the Set. Example of LinkedHashSet: importjava.util.LinkedHashSet;publ...
然后可以使用 HashSet 构造函数将 List 对象转换为 HashSet。 Java实现 // Java program to convert comma // separated string to HashSet importjava.util.Arrays; importjava.util.HashSet; importjava.util.List; publicclassStringToHashSetExample{ publicstaticvoidmain(String[]args){ Stringstr="1,2,3,...
importjava.util.HashSet;publicclassHashSetExample{publicstaticvoidmain(String[]args){// 创建 HashSet 并初始化HashSet<String>fruits=newHashSet<>();fruits.add("Apple");fruits.add("Banana");fruits.add("Orange");fruits.add("Apple");// 重复元素,不会添加// 输出 HashSet 的元素System.out.prin...

Java中HashSet使用源码演示 如下的代码段是关于Java中HashSet使用演示的代码,希望对各位朋友有所好处。 import java.util.HashSet; public class myHashsetExample { public static void main(String[] args) { HashSet<String> languages = new HashSet<String>();...
importjava.util.*; classLinkedHashSetExample{ publicstaticvoidmain(Stringargs[]) { // create an instance of LinkedHashSet LinkedHashSet<String>lhs =newLinkedHashSet<String>(); // insert element in LinkedHashMap lhs.add("Amit"); // insert first null key ...
要使用HashSet类,首先需要导入java.util包。然后可以创建一个HashSet对象,并通过add()方法向集合中添加元素。例如下面的代码创建了一个存储整数的HashSet,然后添加了一些元素: importjava.util.HashSet;publicclassHashSetExample{publicstaticvoidmain(String[]args){HashSet<Integer>set=newHashSet<>();set.add(10...
We added elements in the incremental order of “one”, “two” etc. But, the output has different order. The output is not sorted (for example: alphabetically). Hence, with such an easy example, we have provedHashSets allow Unique Elements, theyDo not Guarantee OrderandDo not support Sor...
