public class Test {
static int avg(int number1,int number2)throws Exception{
?if(number1<0||number2<0){
? throw new Exception("不可以使用負數");
?}
?if(number1>100||number2>100){
? throw new Exception("數值太大");
?}
?return (number1+number2)/2;
}
public static void main(String[] args) {
?// TODO Auto-generated method stub
?try{
? int result=avg(102,150);
? System.out.println(result);
?}catch(Exception e)
?{
?e.printStackTrace();
? System.out.println(e);
?}
}
}
試試這個，應該可以
