What is wrong with this simple running JAVA class? [duplicate]

Question

I don't know why I can't run compiled java class. Even very simple. Please see below.

C:\javatest>echo %CLASSPATH%
C:\Program Files\Java\jdk1.7.0_45\bin; C:\Program Files\Java\jdk1.7.0_45\jre\bin


C:\javatest>echo %JAVA_HOME%
C:\Program Files\Java\jdk1.7.0_45

C:\javatest>cat hello.java
class hello{
public static void main(String[] agrs){
    System.out.println("Hello world");
}
}
C:\javatest>javac hello.java

C:\javatest>java hello.class
Error: Could not find or load main class hello.class

C:\javatest>java -cp . hello.class
Error: Could not find or load main class hello.class

C:\javatest>

JAVA in windows path C:\Program Files\Java\jdk1.7.0_45\bin

Please help.

EDITED

C:\javatest>java hello
Error: Could not find or load main class hello

C:\javatest>java.exe hello
Error: Could not find or load main class hello
