异常和异常处理

public static void main(String[]args){
   String[]str={"123","456","567","12@","abc","245","58a"};

   try{
      for(String string:str){
          System.out.println(string);
         
          //将字符串转化为整数类型
          System.out.println("+"+Integer.parseInt(string)*2);
      }
   }catch(NumberForatException e){
      System.out.println(e.toString());//异常名称，异常信息
   }

   for(String string:str){
      System.out.println(string);
      try{//捕捉异常
          System.out.println("+" + Integer.parseInt(string) * 2);
      }catch(NumberForatException e){
          System.out.println("-" + string);
      }
   System.out.println("异常处理完毕，程序正常退出！！");
   }
}
