Question

我要在Eclipse中导入现有项目。我收到此错误，不知道如何解决。可能是因为JRE或JDK版本。我对此很陌生，所以我很失落。我正在寻找建议...

以下是显示的错误：

double a[4] = { 0, 0, 0, 0 };
double b[4] = { 0, 0, 0, 0 };
double w[8] = { 1, 0, 0, 0, 0, 0, 0, 0 };
int m = 3;
int l = 8;

fft(a, b, w, m, l);

这是类路径

.classpath

不要再问第二个问题。 Having a problem in building an existing java project in eclipse

该消息表明.project文件不是有效的库。它不是jar文件，也不是包含类文件的文件夹结构的目录。从项目的Java构建路径中删除该条目。
