JAVA throws

//仅作为学习笔记

class Demo
{
	int div(int a,int b) throws Exception//在功能上通过throws的关键字声明该功能可能出现问题
	{
		return a/b;
	}
}


class ExceptionDemo
{
		public static void main(String[]args) //throws Exception
		{
			Demo d = new Demo();

		try
		{
				int x = d.div(4,0);
				//int x = d.div(4,1);
				System.out.println("x="+x);	
		}
		catch (Exception e)
		{
			System.out.println(e.toString());
		}
		
			System.out.println("Over");
