finally節とreturn/throw

Last updated at Posted at 2016-07-25



//finally節はtry節のreturn/throwを上書きする。
//default文はcase文のreturn/throwを上書きしない(比較)。



class TestFinally{	
	void method() throws Throwable{
		try{
			throw new Exception();
		}finally{
			throw new Throwable();
		}
	}
}
class TestDefault{
	void method() throws Throwable{
		switch(123){
		case 123:
			throw new Exception();
		default:
			throw new Throwable();
		}
	}	
}
public class Test {
    public static void main(String[] args) {
        try{
        	(new TestFinally()).method();	//①
        	(new TestDefault()).method();	//②
        }catch(Exception e){
        	//②はこちらでcatchされる。
        	System.out.println(e);
        }catch(Throwable e){
        	//①はこちらでcatchされる。
            System.out.println(e);
        }
    }
}
