Arrays.parallelPrefix(arr2,new IntBinaryOperator()有错误，应该怎么改呀
package lianxi;
import java.util.Arrays;
public class Lianxi
{
public static void main(String[] args)
{
int[] arr1=new int[]{3,-4,25,16,30,18};
Arrays.parallelSort(arr1);
System.out.println(Arrays.toString(arr1));
int[] arr2=new int[]{3,-4,25,16,30,18};
Arrays.parallelPrefix(arr2,new IntBinaryOperator()
{
public int applyAsInt(int left,int right)
{
return left*right;
}
}
);
System.out.println(Arrays.toString(arr2));
}
}
