在继承中的异常

public interface ExceptionInterface {
	
	void exceptionedMethod()throws Exception;

}

public abstract class  ExceptionAbstractClass implements ExceptionInterface{

	public void exceptionedMethod() throws/* Exception,*/UnsupportedOperationException {
		
	}
	
}

public class ExceptionClass extends ExceptionAbstractClass {
	
	public void exceptionedMethod() throws Exception {
		
	}

}

 最后一个会报错。

PS:UnsupportedOperationException :
