java基础面试题-中级20题答案解析版​​​​​​​

正确答案是：A

如果有try  catch块则选C

举例说明：

public class Demo {
	public static void main(String args[]) { 
		 Demo1.print();
		 Demo2.print();
	}
}
class Demo1 {
	public static void print(){//加上 static 直接类名点调用，省去new的步骤
		System.out.println("this is Demo1 start");
		try {
			System.out.println("this is Demo1 try");
			throw new Exception();//人为抛出异常
//			System.out.println("此处永远不能到达，编译报错");
		} catch (Exception e) {
			System.out.println("this is Demo1 catch");
		}finally{
			System.out.println("this is Demo1 finally");
		}
		System.out.println("this is Demo1 end");
	}
}
class Demo2 {
	public static void print(){
		System.out.println("this is Demo2 start");
		try {
			System.out.println("this is Demo2 try");
		} catch (Exception e) {
			System.out.println("this is Demo2 catch");
		}finally{
			System.out.println("this is Demo2 finally");
		}
		System.out.println("this is Demo2 end");
	}
}
