trycatchfinally.java

我在学习JAVA的讲义

public class TryCatchFinally
{   public static void main(String args[ ])
    {   Method(0);
        Method(1);
        Method(2);
    }
    static void Method(int a)
    {   System.out.println("调用方法method("+a+")");
        try
        {   if(a==0)
            {   System.out.println("\t没有异常产生，正常退出");
                return;
            }
            else if(a==1)
            {   int i=0;
                int j=3/i;
            }
            else if(a==2)
            {   int iArray[ ]=new int[4];
                iArray[4]=3;
            }
        }
        catch(ArithmeticException e)
        {   System.out.println("\t捕获异常："+e.getMessage( ));
        }
        catch(ArrayIndexOutOfBoundsException e)
        {   System.out.println("\t捕获异常："+e);
        }
        catch(Exception e)
        {   System.out.println("\t产生的异常已被处理，该 catch 块不会被执行。");
        }
        finally
        {   System.out.println("\t finally 块总是被执行的。");
        }
    }
}
