一 代码

import java.util.Arrays;

public class LambdaArrays
{
   public static void main(String[] args)
   {
      String[] arr1 = new String[]{"java" , "fkava" , "fkit", "ios" , "android"};
      Arrays.parallelSort(arr1, (o1, o2) -> o1.length() - o2.length());
      System.out.println(Arrays.toString(arr1));
      int[] arr2 = new int[]{3, -4 , 25, 16, 30, 18};
      // left代表数组中前一个所索引处的元素，计算第一个元素时，left为1
      // right代表数组中当前索引处的元素
      Arrays.parallelPrefix(arr2, (left, right)-> left * right);
      System.out.println(Arrays.toString(arr2));
      long[] arr3 = new long[5];
      // operand代表正在计算的元素索引
      Arrays.parallelSetAll(arr3 , operand -> operand * 5);
      System.out.println(Arrays.toString(arr3));
   }
}

二 运行

[ios, java, fkit, fkava, android]
[3, -12, -300, -4800, -144000, -2592000]
[0, 5, 10, 15, 20]
