如果需要一个可变大小的List,可以将Arrays.asList()的结果传递给ArrayList的构造函数。 2. 示例代码:Array到List的转换过程 示例1:使用Arrays.asList() java import java.util.Arrays; import java.util.List; public class ArrayToListExample { public static void main(String[] args) { String[] array = ...
在Java中,使用ArrayList进行转换通常是指将一个ArrayList对象转换为另一种类型的对象。这里有一个简单的示例,展示了如何将一个ArrayList<String>转换为ArrayList<Integer>: 代码语言:java 复制 importjava.util.ArrayList;importjava.util.List;importjava.util.stream.Collectors;publicclassArrayListConversion{publicstaticvoi...
int[] number = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; List<Integer> list = new ArrayList<>(); for (int i : number) { list.add(i); } In Java 8, you can use the Stream APIs to do the boxing and conversion like this : List<Integer> list = Arrays.stream(number).boxed(...
TheArrayUtils.toObject()converts an array of primitive values to array of object types. Then we can collect the array of objects toListusing the standardArrays.asList()method. int[]intArray=newint[]{0,1,2,3,4,5};List<Integer>list=Arrays.asList(ArrayUtils.toObject(intArray)); Do not ...

However, this method involves additional steps of conversion, which can be time-consuming for large arrays. Here is an example of how an array can be converted to an ArrayList, an element can be removed, and then the ArrayList can be converted back to an array in Java: import java.util....
util.ArrayList; import java.util.List; /* * Here we will learn to convert List to Arrays. */ public class ListToArrayType { /* * Note*: Here in this code Autoboxing is done also generics is getting used. Because of generics * Casting is not required. */ public static void main...
