我在“handDetailList.each”行抛出了一个强制转换异常。我不明白为什么我的代码试图将列表转换为“手”类?在我看来,有时 Groovy 会在铸造方面做一些奇怪的事情......?
private Hand buildHands(List handDetailList) {
def parsedHand = new Hand()
parsedHand.setTableName(handDetailList.get(1))
handDetailList.each {
}
}
我得到以下异常(我已经编辑了异常,第 70 行是“handDetailList.each {”):
Exception in thread "main" org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object <details of the list, omitted> with class 'java.util.ArrayList' to class 'gameMechanics.Hand' due to: groovy.lang.GroovyRuntimeException: Could not find matching constructor for: gameMechanics.Hand(java.lang.String,........
