在Java while循环条件中分配变量？ [英] Assign variable in Java while-loop conditional?

问题描述

我有一个方法可以进行大量的检查和计算，并返回一个自定义类returnMessage。 returnMessage有2个布尔值和一个String。我想要做的是在我的主类的while循环中运行此方法，并在while循环最后一次终止后访问returnMessage对象。

I have a method that does a lot of checking and computation and returns a custom class, returnMessage. returnMessage has 2 booleans and a String. What I want to do is run this method in a while loop from my main class and have access to the returnMessage object after the while loop terminates for the last time.

在php中，这将是

while ( $returned = myObject->myMethod()->finished )
{

}

if( $returned -> finished == FALSE)
{
...
}

但是尝试像这样分配在java中给我一个布尔预期的错误（上面可能有php错误，已经晚了：D）

However trying to assign like this gives me a boolean expected error in java (there might be php errors in the above, it's late :D )

推荐答案

我们需要看到更多你的代码，但猜一点我觉得这样的事情会起作用：

We need to see more of your code, but guessing a little I think something like this would work:

ReturnMessage returned;
while (!(returned = myObject.myMethod()).finished) {

}
if (!returned.finished) {

}
