throws语句是在方法的声明中使用来抛出异常，throw语句是在方法体内使用抛出的异常
自定义异常
class 类名 extends Exception
{
public MyException()
{
}
public MyException(String s)
{
super(s);
}
}
自定义异常：
package 异常处理;
public class YiChang5 {
public String deiFen(int fen) throws MyException
{
if(fen>=0&&fen<=100)
{
return "正常";
}
else
{
throw new MyException("错误输入");
}
}
public static void main(String[] args) {
// TODO Auto-generated method stub
YiChang5 yc = new YiChang5();
try
{
String s = yc.deiFen(68);
System.out.println(s);
String ss = yc.deiFen(123);
System.out.println(ss);
}
catch(ArrayIndexOutOfBoundsException e)
{
System.out.println("该程序发生了数组下标越界异常");
}
catch(MyException e)
{
System.out.println("异常信息为:" + e.getMessage());
}
catch(Exception ee)
{
System.out.println("该程序发生了异常");
}
finally
{
System.out.println("该语句是肯定执行的");
}
}
}
