NotExistingClass不在当前类路径

  1. package com.javabook.classloader.found;
  2. public class NotExistingClass
  3. {
  4. }

尝试去加载NotExistingClass类型

  1. package com.javabook.classloader.notfound;
  3. /**

  8.  */
  9. public class ClassNotFoundExceptionDemo {
  11.     public static void main(String[] args) {
  12.         try {
  13.             Class.forName("com.javabook.classloader.found.NotExistingClass");
  14.         } catch (ClassNotFoundException e) {
  15.             e.printStackTrace();
  16.         }
  17.     }
  18. }
