如果finally块中有return语句的话，它将覆盖掉函数中其他return语句。
public class Demo{ public static void main(String args[]){ int num = 10; System.out.println(test(num));}public static int test(int b){ try { b += 10; return b; } catch(RuntimeException e) { } catch(Exception e2) { } finally { b += 10; return b; } }}原文：https://www.cnblogs.com/67373cyf/p/11264492.html
