Java代码实现

public static int intDiv(int a, int b) {if (b != 0) {return a / b;} else {throw new ArithmeticException("Division by zero is not allowed.");}
}public static void main(String[] args) {int a = 500000;int b = 50;System.out.println("Result of intDiv(" + a + ", " + b + "): " + intDiv(a, b));a = 500001;b = 50;System.out.println("Result of intDiv(" + a + ", " + b + "): " + intDiv(a, b));a = 500050;b = 50;System.out.println("Result of intDiv(" + a + ", " + b + "): " + intDiv(a, b));
}

输出结果

Result of intDiv(500000, 50): 10000
Result of intDiv(500001, 50): 10000
Result of intDiv(500050, 50): 10001
