运行以下代码
public static void main(String[] args) { System.out.println(test());}public static String test(){ try { int t = 1 / 0; System.out.println("============"); } catch (Exception e) { System.out.println("-------------"); return "exception"; } finally { System.out.println("++++++++++++"); } return "";}输入:
D:\java1.8\jdk1.8.0_60\bin\java.exe ...Connected to the target VM, address: '127.0.0.1:49697', transport: 'socket'-------------++++++++++++exceptionDisconnected from the target VM, address: '127.0.0.1:49697', transport: 'socket'Process finished with exit code 0论断:
- 依据输入后果能够看出即便catch代码块中蕴含return也同样会执行finally代码块中的内容
finally代码块执行结束后会继续执行catch代码块中的return语句
那么finally代码块中同样蕴含一个return语句又会怎么执行呢?
public static void main(String[] args) { System.out.println(test());}public static String test() { try { int t = 1 / 0; System.out.println("============"); } catch (Exception e) { System.out.println("-------------"); return "exception"; } finally { System.out.println("++++++++++++"); return "***************"; }}输入:

从运行后果中能够看出若finally代码块中蕴含了return语句则不会再去执行catch中的return语句
