异常注意事项:finally有return语句
- 如果finally有return语句,永远返回finally中的结果,避免该情况.
public class Demo02Exception {
public static void main(String[] args) {
int a = getA();
System.out.println(a);
}
//定义一个方法,返回变量a的值
public static int getA(){
int a = 10;
try{
return a;
}catch (Exception e){
System.out.println(e);
}finally {
//一定会执行的代码
a = 100;
return a;
}
}
}
