使用Java8通过LongStream批处理ArrayList

import java.util.ArrayList;
import java.util.List;
import java.util.stream.LongStream;

List<Long> arrayList = new ArrayList<>();
arrayList.add(1L);
arrayList.add(2L);
arrayList.add(3L);
// 添加更多元素...

LongStream longStream = arrayList.parallelStream().mapToLong(Long::valueOf);

longStream = longStream.filter(num -> num % 2 == 0) // 过滤偶数
                       .map(num -> num * 2) // 将每个元素乘以2
                       .sorted(); // 排序

List<Long> processedArrayList = longStream.boxed().collect(Collectors.toList());

import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;
import java.util.stream.LongStream;

public class ArrayListProcessing {
    public static void main(String[] args) {
        List<Long> arrayList = new ArrayList<>();
        arrayList.add(1L);
        arrayList.add(2L);
        arrayList.add(3L);
        // 添加更多元素...

        LongStream longStream = arrayList.parallelStream().mapToLong(Long::valueOf);
        longStream = longStream.filter(num -> num % 2 == 0) // 过滤偶数
                               .map(num -> num * 2) // 将每个元素乘以2
                               .sorted(); // 排序

        List<Long> processedArrayList = longStream.boxed().collect(Collectors.toList());
        System.out.println(processedArrayList);
    }
}
