Java 运算符优先级表达式求值
我有以下变量减速度、赋值和变量减速度
变量 e 是一个表达式语句，它应该返回表达式中求值变量的值；
e 变量中运算符的优先顺序是什么？
计算出来等于= 60；
用计算器我得到422；
int a, b, c, d;
a = 10;
b = 2;
c = 1;
d = 20;
e = a + b * d / c + a + b / d;
e = 10 + 2 * 20 / 1 + 10 + 2 / 20;
e = 60;
I have the following variable decelrations, assignments and variable declerations
variable e is an expression statement which should return the value of the evaulated variables in the expression;
What is the order of precdence of the opperators in the e variable?
Computed it equals = 60;
With a calculator I get 422;
int a, b, c, d;
a = 10;
b = 2;
c = 1;
d = 20;
e = a + b * d / c + a + b / d;
e = 10 + 2 * 20 / 1 + 10 + 2 / 20;
e = 60;

实际上答案是
60.1，但由于变量是int，因此显示60。事情发生如下Actually the answer is
60.1but sincevariablesare int its showing60. It is happening as below这里是概述运算符优先级的链接。至于您的结果，这也可以归因于整数除法（它取结果的下限；例如，
2/20 = 0）。Here is a link outlining operator precedence. As for your result, this can also be attributed to integer division (which takes the floor of the result; for instance,
2/20 = 0).就像在学校一样，乘法和除法优先于加法。所以你有：
Just like in school, multiplication and division have priority over addition. So you have:
