• 在try范围执行时抛出异常后，try里面剩余的代码不再执行，直接跳到catch

  public class returnDemo{
    public static void main(String[] args)
    {
      Finally e = new Finally();
      System.out.println(e.tryThis());
    }
    
    public int tryThis()
    {
      try{
        System.out.println("1");
        throw new Exception();
        return 1;
      }catch(Exception ex){
        System.out.println("2");
        return 2;
      }finally{
        System.out.println("4");
        return 3;
      }
      //System.out.println("5");  
    }
  }

• finally的return优先级最高
  public class Finally{
    public static void main(String[] args)
    {
      Finally e=new Finally();
      System.out.println(e.tryThis());
    }
    
    public int tryThis()
    {
      try{
        System.out.println("1");
        throw new Exception();
      //return 1;
      }catch(Exception ex){
        System.out.println("2");
        return 2;
      }finally{
        System.out.println("4");
        return 3;
      }
    }
  }
