Here's the breakdown: Option A:0- This is the correct default value for an uninitializeddoublevariable in Java. It represents the numeric value zero. Option B:1- This is not the default value for adoublevariable
在Java中,声明一个double变量的基本语法如下: doublevariableName; 1. 这里,variableName是变量名称,必须遵循Java的命名规则。我们还可以在声明时赋初值,例如: doubleprice=49.99; 1. 实际问题 假设你是一名旅行策划者,正在设计一个旅行预算计算器。用户需要输入一些信息,例如旅行天数、每晚住宿费以及每日饮食费用,然后...
In this example, twodoublevariablespiandgravityare declared and initialized with values 3.14159 and 9.81 respectively. The program then prints these values.

1、在java语言中整数默认是int类型,小数默认是double类型 2、byte,short,char类型进行运算时,会先转为int类型进行运算。 3、要想定义一个long类型的数据,在值的末尾处添加一个l或者L,表示这是一个long类型的数据,推荐使用L 4、要想定义一个float类型的数据,在值的末尾处添加一个f或者F,表示这是一个float类型...
