public Integer(int value) { this.value = value; } 引⽤⽹上⼀位博主的解释: JAVA设计者的初衷估计是这样的:如果开发者要做计算,就应该使⽤primitive value如果开发者要处理业务问题,就应该使⽤object,采⽤Generic机制;反正JAVA有auto-boxing/unboxing机制, 对开发者来讲也不需要注意什么。然后为了弥补...

How do I represent minimum and maximum values for integers in Python? In Java, we have Integer.MIN_VALUE and Integer.MAX_VALUE.回答1Python 3 In Python 3, this question doesn't apply. The plain int type is unbound. However, you might actually be looking for information about the current ...
