将上面的步骤结合起来,我们可以实现一个完整的程序来处理整数溢出。 importjava.math.BigInteger;publicclassIntOverflowHandler{publicstaticbooleanisWithinIntRange(longnumber){returnnumber>=Integer.MIN_VALUE&&number<=Integer.MAX_VALUE;}publicstaticBigIntegerhandleOverflow(longnumber){returnBigInteger.valueOf(number);...

(1)设计Integer封装类型的原因是: Java本身就是一个面向对象的编程语言,一切操作都是以对象作为基础,如像ArrayList,HashSet,Hashtable,HashMap等集合类中存储的元素,只支持存储Object类型,又如同泛型的设计,统统表现出了Java对于封装类型的重用,而对于int,byte,short,float,char,long,double这种基本数据类型其实用的很...

一般采用二进制补码进行表示和运算,MIN_VALUE = 0x80000000 和 MAX_VALUE = 0x7fffffff 就是补码表示的Integer的最小值(-2^31)和最大值(2^31-1)。至于为什么采用补码表示,简单的说就是方便运算,详细可自行Google一下或找本基础教材翻一下。至于Integer的最大值最小值为什么是这两个数,这是因为Java语言规范...
