获取java.lang.ClassNotFoundException

我能够编译代码，但在运行时通过classnotfound

C:\Users\Desktop\New>javac-classpath java-mail-1.4.4.jar SendMail.java

C:\Users\Desktop\New>java-classpath java-mail-1.4.4.jar SendMail

Exception in thread "main" java.lang.NoClassDefFoundError: SendMail
Caused by: java.lang.ClassNotFoundException: SendMail
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:307)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: SendMail.  Program will exit.

您能建议如何解决此问题吗？

尝试使用：

窗口

java -classpath java-mail-1.4.4.jar;. SendMail
                    note this  ----^

---

尝试使用下面的命令

编译java类

javac-classpath。；；Abc.java

执行java类

---

java-classpath。；；Abc

是否

SendMail.class

存在于

C:\Users\Desktop\New

路径中？类路径中缺少mail.jar。@VaibhavJain否，则会引发

java.lang.ClassNotFound

异常
