找不到符號拋出IndexOutOfBoundException

Question

我有以下簡單的類：

public class Polynomial { 
    private double[] c; 
    public double get(int i) throws IndexOutOfBoundException { return c[i]; } 
    public void set(int i, double a) throws IndexOutOfBoundException, ArithmeticException { c[i] = a; } 
} 

編譯時我收到此錯誤：

Polynomial.java:39: error: cannot find symbol 
    public double get(int i) throws IndexOutOfBoundException { return c[i]; } 
            ^
    symbol: class IndexOutOfBoundException 
    location: class Polynomial 
Polynomial.java:42: error: cannot find symbol 
    public void set(int i, double a) throws IndexOutOfBoundException, ArithmeticException { c[i] = a; } 
              ^
    symbol: class IndexOutOfBoundException 
    location: class Polynomial 
2 errors 

爲什麼會收到cannot find symbol爲異常IndexOutOfBoundException？自從我上次用java編程已經有一段時間了，但我沒有看到任何錯誤。

這是IndexOutOfBoundsException，而不是IndexOutOfBoundException。
