例如,在一个32位有符号整数(signed integer)中,其取值范围是从-2,147,483,648到2,147,483,647。如果运算结果超出了这个范围,就会发生整数溢出。 2. 分析导致“signed integer overflow: 2147483647 + 1 cannot be represented”错误的原因 这个错误发生的原因是因为你在尝试将一个已经达到32位有符号整数最大值...

所以趁此机会深入了解一下java中的Integer类。 Integer的界限范围与int类型是一致的。都是0x7fffffff~0x80000000。Integer类中是这样声明的。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 /** * A constant holding the minimum value an {@code int} can * have, -231. */publicstaticfinal intMIN...

* * @param value the value to be represented by the * {@code Integer} object. */ public Integer(int value) { this.value = value; } Integer中定义了一个int类型的value属性。由于该属性是final类型,因此需要通过构造方法来赋值。这个逻辑非常简单,没有太多要关注得。 结论: 当通过new关键字构建一...

This is so because .1 cannot be represented exactly as a double (or, for that matter, as a binary fraction of any finite length). Thus, the long value that is being passed in to the constructor is not exactly equal to .1, appearances notwithstanding. ...
