【自动化__持续集成】___java___finally

一、代码如下

package www.wujianbotwo;

public class Demo14 {

public static void main(String[] args) {
// TODO Auto-generated method stub
Demo14 demo14= new Demo14();
demo14.nullTest();

}

private void nullTest() {
// TODO Auto-generated method stub
try {
String s= null;
//int x= 9 / 0;
System.out.println(s.length());
//System.out.println(x);
} 
catch (ArithmeticException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (NullPointerException e) {
// TODO Auto-generated catch block
//e.printStackTrace();
System.out.println(e);
System.out.println("字符变量没有初始化");
}
finally {
System.out.println("不管有没异常，我都会执行");
}
}

}
