public void mySort(Object [] obj) {
     Arrays.sort(obj, null);     // this sorts based on compareTo() 
                                 // method of comparable object
}

我的问题是如何通过Field字段更改以下函数来对数组进行排序.我已经尝试了许多不同的方法来实现它,只需将代码放在下面,代表我想要做的事情.

// this function should be used to sort a generic array of T objects, to be

public static <T> void mySort2(T [] obj, Field field) {
    Collections.sort(obj, new Comparator<T>(){
