This method will always cache values in the range -128 to 127, inclusive, and may cache other values outside of this range. 此⽅法将始终缓存-128到127(包括端点)范围内的值,并可以缓存此范围之外的其他值 缓存设计 valueOf ⽅法中 IntegerCache.low = -128; IntegerCache.high = 127 ; 也就是...

首先,我们需要在Java代码中导入相关的类。在本例中,我们需要导入java.lang.Integer类。 importjava.lang.Integer; 1. 步骤2:使用new关键字创建一个Integer对象 接下来,我们可以使用new关键字创建一个Integer对象。new关键字用于实例化一个类,并返回一个对应的对象。
