我刚学Java,用书抄了一个程序,太简单:
public class app {
public static void main(String[] args)
{
System.out.println("hello world! java");
}
}编译,执行一下,
F:\JAVA\Test>javac app.java
F:\JAVA\Test>java app
Exception in thread "main" java.lang.NoClassDefFoundError: app错误说明如上,请指点!
public class app {
public static void main(String[] args)
{
System.out.println("hello world! java");
}
}编译,执行一下,
F:\JAVA\Test>javac app.java
F:\JAVA\Test>java app
Exception in thread "main" java.lang.NoClassDefFoundError: app错误说明如上,请指点!
我在Eclipse环境下可以运行,但在SDK下就不行!
F:\JAVA\Test>javac app.java
//编译通过，表明PATH路径设置正确！F:\JAVA\Test>java app
Exception in thread "main" java.lang.NoClassDefFoundError: app
//99.99%是你的CLASSPATH设置有误！！！
