Answer 1

publicYear(intyear) {
101:if ((year < SerialDate.MINIMUM_YEAR_SUPPORTED)
102:|| (year > SerialDate.MAXIMUM_YEAR_SUPPORTED)) {
103:
104:thrownewIllegalArgumentException(
105:"Year constructor:year (" + year + ") outside valid range.");
106:}
107:this.year = (short) year;
108:peg(Calendar.getInstance());
109:}
以上是jfree的Year类的源代码,很清楚了 你在构造year对象时,传入的值（109）不在范围之内
类org.jfree.date.SerialDate中定义的范围为：
103:/** The lowest year value supported by this date format.*/
104:public static final int MINIMUM_YEAR_SUPPORTED = 1900;
105:
106:/** The highest year value supported by this date format.*/
107:public static final int MAXIMUM_YEAR_SUPPORTED = 9999;
