找不到符号抛出IndexOutOfBoundException

Question

我有以下简单类：

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; }
}

编译时我收到此错误：

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

为什么我cannot find symbol会收到异常IndexOutOfBoundException？自从我上次用java编程以来已经有一段时间但我在这里看不出任何错误。

它是IndexOutOfBoundsException，而不是IndexOutOfBoundException。

你错过了一个S
