C语言，想问问这题为什么选A
#define f(x) x*x#include /*int main(){int i;i=f(2+2)/f(1+1);printf("%d\n",i);}*///这是原题的代码int main(){int i;i=2+2*2+2/1+1*1+1;printf("%d\n",i);}//这应是宏展开后的代码我测试了一下，两种运行结果完全一致，都是10，答案可能有问题，你自己试试。
在java中boolean具体怎么使用？
boolean是java中的布尔型（逻辑型）数据类型，在java中boolean值只能是true和false，而不能用0和1代替，并且一定要小写。布尔值true代表“真”，false代表“假”。一般关系运算符会返回布尔值的结果。另外，数值的0、-0、特殊值的null、NaN、undefined以及空字符（""）都会被解释为false，其他值则会被解释为true。扩展资料java中创建boolean对象的方法：1、使用关键词new来定义Boolean对象。下面的代码定义了一个名为myBoolean的逻辑对象：varmyBoolean=newBoolean()varmyBoolean=newBoolean()注释：如果逻辑对象无初始值或者其值为0、-0、null、""、false、undefined或者NaN，那么对象的值为false。否则，其值为true（即使当自变量为字符串"false"时）！2、下面的所有的代码行均会创建初始值为false的Boolean对象。varmyBoolean=newBoolean();varmyBoolean=newBoolean(0);varmyBoolean=newBoolean(null);varmyBoolean=newBoolean("");varmyBoolean=newBoolean(NaN);3、下面的所有的代码行均会创初始值为true的Boolean对象：varmyBoolean=newBoolean(1);varmyBoolean=newBoolean(true);varmyBoolean=newBoolean("true");varmyBoolean=newBoolean("false");varmyBoolean=newBoolean("BillGates");参考资料来源：百度百科——Boolean
java中boolean是什么意思
亲亲您好感谢您的耐心等待，Java中的boolean其实就是c中的bool型（逻辑型）数据类型。在java中，boolean值只能是true和false，⽽不能⽤0和1代替，并且⼀定要⼩写。要注意到的是，数值的 0、-0、特殊值的 null、NaN、undefined 以及空字符（""）都会被解释为 false ，其他值则会被解释为 true 呢。[开心]【摘要】

亲亲您好，java中创建布尔对象：1、使用关键字new定义Boolean对象。 下面的代码定义一个名为myBoolean的逻辑对象。var myBoolean=new Boolean (var myBoolean=new Boolean (注释：如果逻辑对象没有初始值，或者值为0、-0、null、''、false、undefined或NaN，则对象的值为false。 否则，即使参数为字符串“false”，值也为true！【回答】
亲亲您好，1)对于非boolean类型的参数，getter和setter方法命名的规范是以get和set开头2)对于boolean类型的参数，setter方法是以set开头，但是getter方法命名的规范是以is开头3)包装类自动生成的getter和setter方法的名称都是getXXX()和setXXX()a. 其实javaBeans规范中对这些均有相应的规定，基本数据类型的属性，其getter和setter方法是getXXX()和setXXX，但是对于基本数据中布尔类型的数据，又有一套规定，其getter和setter方法是isXXX()和setXXX。但是包装类型都是以get开头b. 这种方式在某些时候是可以正常运行的，但是在一些rpc框架里面，当反向解析读取到isSuccess()方法的时候，rpc框架会“以为”其对应的属性值是success，而实际上其对应的属性值是isSuccess，导致属性值获取不到，从而抛出异常呢。[开心]【回答】
