java.lang.ClassNotFoundException running from the console

Question

I compiled the Java files:

source code
 folder1
  a.java
  b.java
 folder2
  c.java
  d.java
 Main.java

And I want to run them in this folder:

bin
 folder1
  a.class
  b.class
 folder2
  c.class
  d.class
 Main.class

I tried java Main and the program runs. But when I press a key, it says:

java.lang.ClassNotFoundException: CFactory

where CFactory is a Java file called by Main.java like this: (Class.forName("CFactory").newInstance())

How to fix the problem, and run it as normal?

run.bat
mkdir abstractfactorypattern\abstractcommandfactory
mkdir abstractfactorypattern\abstractfoodfactory
mkdir commandpattern
mkdir mementopattern
mkdir stock

cd ..\source code

javac abstractfactorypattern\abstractcommandfactory\*.java
javac abstractfactorypattern\abstractfoodfactory\*.java
javac commandpattern\*.java
javac mementopattern\*.java
javac stock\*.java

move abstractfactorypattern\abstractcommandfactory\*.class ..\bin\abstractfactorypattern\abstractcommandfactory
move abstractfactorypattern\abstractfoodfactory\*.class ..\bin\abstractfactorypattern\abstractfoodfactory
move commandpattern\*.class ..\bin\commandpattern
move mementopattern\*.class ..\bin\mementopattern
move stock\*.class ..\bin\stock`enter code here`
move *.class ..\bin

cd ..\bin
java AIMS

Answer 1

That error means Java cannot find a file called CFactory.class . Do you have it somewhere?

Once you find where it is, execute your Java program like this (assuming your file is at C:/path/CFactory.class ):

java -classpath .;C:/path/ Main

解决方案核心命令c = Class.forName（“ package1.package2。” + x）.newInstance（）;
