这是什么错误，如何解决

[shanyou]

class subStringBuffer
{
public static void main(String[] args)
{
StringBuffer buf=new StringBuffer("The Java Class Libraries");
System.out.println(buf.substring(4,8));

System.out.println(buf.substring(9));
}
}
java subStringBuffer出现如下错误
---------- java ----------
java.lang.NoClassDefFoundError: subStringBuffer
Exception in thread "main" Normal Termination
Output completed (0 sec consumed).
