My insertion sort method is declared using this statement:
我的插入排序方法是使用以下语句声明的:
public static <AnyType extends Comparable<? super AnyType>>
void insertionSort(AnyType[]a){
I am having trouble understanding how applying this generic array will allow me to use an array of primitive type int
我无法理解如何应用这个通用数组将允许我使用基本类型int数组
How would I call this method with int[] as my parameter or at least how would it be used to sort an int array.
我如何使用int []作为我的参数调用此方法,或者至少如何使用它来对int数组进行排序。

Use a wrapper class - Integer. There is something called autoboxing which means that if you pass an argument of primitive type int it will convert automatically to Integer :-)
使用包装类 - 整数。有一种称为自动装箱的东西,这意味着如果你传递一个原始类型int的参数,它将自动转换为整数:-)
