java - 为什么这会给我一个边界错误？

Question

我有一个自定义的“堆”类:

public class Heap<T extends Comparable<T>>
{
    ArrayList<T> heapList;


    public Heap()
    {
        heapList = new ArrayList<T>();

    }

和自定义“Process”类:

public class Process {
    private int processID, timeUnitsRequired, priority, timeOfArrival;

    public Process(int processID, int timeUnitsRequired, int priority, int timeOfArrival) {
        this.processID = processID;
        this.timeUnitsRequired = timeUnitsRequired;
        this.priority = priority;
        this.timeOfArrival = timeOfArrival;
    }

但是如果我尝试创建一个新的进程堆，例如 Heap<Process> processHeap = new Heap<Process>();我收到以下错误:

Bound mismatch: The type Process is not a valid substitute for the bounded parameter > of the type Heap

这是为什么呢？我似乎无法弄清楚。

流程未实现 Comparable
