java - 找不到符号抛出 IndexOutOfBoundException

Question

我有以下简单的类:

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; }
}

编译时出现此错误:

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

为什么我得到 cannot find symbol 异常 IndexOutOfBoundException？距离上次我用 Java 编程已经有一段时间了，但我没有发现任何问题。

是IndexOutOfBoundsException，不是IndexOutOfBoundException。

你少了一个S
