一.C语言错误处理方法 1.返回值(if … else语句判断错误) 2.errno(linux 系统调用) 3.goto语句(函数内局部跳转) 4.setjmp.longjmp(Do not use setjmp and longjmp in C++ programs; these functions do not support C++ object semantics. ) #define _JBLEN 16 typedef _JBTYPE jmp_buf[_JBLEN]; Saves…

先上代码再进行分析 public class Test { public static void main(String[] args) { try{ int i = 100 / 0; System.out.print(i); }catch(Exception e){ System.out.print(1); throw new RuntimeException();//这里如果不抛出异常,则最终结果是123 }finally{ System.out.print(2); } System.out…
