我正在尝试使用带有以下命令的命令提示符编译我的 java 文件“check4PrimeTest.java”:
javac -classpath .:junit.jar check4PrimeTest.java
我收到以下错误:
错误:包 junit.framework 不存在 import junit.framework.*;
我不确定为什么会出现此错误,因为我的程序中有 import junit.framework.*。
下面是我的代码:
package check4prime;
// check4PrimeTest.java
//Imports
import junit.framework.*;
public class check4PrimeTest extends TestCase {
//Initialize a class to work with.
private check4Prime check4prime = new check4Prime();

}
