在Java中,處理short類型的異常與處理其他數據類型的異常相似

  1. 使用try-catch語句捕獲異常:
public class ShortExceptionHandling {
    public static void main(String[] args) {
        try {
            short num1 = 10;
            short num2 = 5;
            short result = divide(num1, num2);
            System.out.println("Result: " + result);
        } catch (ArithmeticException e) {
            System.out.println("Error: Division by zero");
        }
    }

    public static short divide(short a, short b) {
        if (b == 0) {
            throw new ArithmeticException("Division by zero");
        }
        return (short) (a / b);
    }
}
  1. 使用throws關鍵字將異常傳遞給調用者:
public class ShortExceptionHandling {
    public static void main(String[] args) {
        short num1 = 10;
        short num2 = 5;
        try {
            short result = divide(num1, num2);
            System.out.println("Result: " + result);
        } catch (ArithmeticException e) {
            System.out.println("Error: Division by zero");
        }
    }

    public static short divide(short a, short b) throws ArithmeticException {
        if (b == 0) {
            throw new ArithmeticException("Division by zero");
        }
        return (short) (a / b);
    }
}
  1. 使用自定義異常處理:
public class ShortExceptionHandling {
    public static void main(String[] args) {
        short num1 = 10;
        short num2 = 5;
        try {
            short result = divide(num1, num2);
            System.out.println("Result: " + result);
        } catch (CustomDivideByZeroException e) {
            System.out.println("Error: " + e.getMessage());
        }
    }

    public static short divide(short a, short b) throws CustomDivideByZeroException {
        if (b == 0) {
            throw new CustomDivideByZeroException("Division by zero");
        }
        return (short) (a / b);
    }
}

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

這些示例展示了如何處理short類型的異常。你可以根據實際需求選擇合適的方法來處理異常。
