在 java 中使用三元运算符添加值时出现错误值

Question

即使我将它添加到 for 循环中，sum 的值也没有改变。 diff 的值为 3

正在打印的值在初始迭代中类似于 3 3 3，应该是 3 6 9。有人可以帮忙吗？

     loop start           
     sum = sum + diff<(26-diff)?diff:(26-diff);
     loop end

Answer 1

计算你的数值表达式的优先顺序是导致你得到错误结果的原因。您当前的陈述等同于：

sum = (sum + diff)<(26-diff)?diff:(26-diff);

等等于 diff 的值，它总是 3。将您的声明更改为：

sum = sum + (diff<(26-diff)?diff:(26-diff));

你会得到你期望的行为。您还可以使用 += 运算符通过将语句更改为：

来解决此问题

sum += diff<(26-diff)?diff:(26-diff);
