2. Define an exception class MyException, which is thrown if the result is not in the range [-32768, 32767] in the method multiply that computes the product of two integers. Define a main class MyExceptionTest that contains the following methods: public static int multiply(int n1, int n2) throws MyException { int result; result=n1*n2; if (result<-32768 || result>32767) throw new MyException(n1+"*"+n2+"的积超出[-32768,32767]的范围！"); return result; } Finally, write codes that can print the product of two integers in the main method of the main class

Here is the implementation of the MyException class and the MyExceptionTest class:

class MyException extends Exception {
    public MyException(String message) {
        super(message);
    }
}

public class MyExceptionTest {
    public static int multiply(int n1, int n2) throws MyException {
        int result = n1 * n2;
        if (result < -32768 || result > 32767)
            throw new MyException(n1 + "*" + n2 + "的积超出[-32768,32767]的范围！");
        return result;
    }

    public static void main(String[] args) {
        int n1 = 10000, n2 = 10000;
        try {
            int result = multiply(n1, n2);
            System.out.println(n1 + " * " + n2 + " = " + result);
        } catch (MyException e) {
            System.out.println(e.getMessage());
        }
    }
}

In the main method, we call the multiply method to compute the product of two integers. If the result is out of the range [-32768, 32767], a MyException will be thrown. We catch the exception and print the error message.
