Question

关于Java自定义异常类。定义MyException继承Exception。

Answer 1

//创建继承父类的自定义异常类MyException：
package bao.ming;

public class MyException extends Exception{
public MyException(String name)
{
super(name);
}

}
//创建公共类NewCustomException类：
package bao.ming;
import bao.ming.MyException;
public class NewCustomException {

public static double avg(int x,int y) throws MyException {

double avg=(double)(x+y)/2;

if(x>=100||x<=0|| y>=100||y<=0){

throw new MyException("my exception:输入参数要在100以内的正整数");

}
return avg;

}

public static void main(String args[]){
double avg=0;
try {
avg=avg(90,99);
System.out.println(avg);
} catch (MyException e) {

e.printStackTrace();
}

}
}
