I am able to compile the java program but not able to run a java program

When I run the java program it gives following error:

Exception in thread "main" java.lang.NoClassDefFoundError: check
Caused by: java.lang.ClassNotFoundException: check
at java.net.URLClassLoader$1.run(URLClassLoader.java:217)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:205)
at java.lang.ClassLoader.loadClass(ClassLoader.java:321)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294)
at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
Could not find the main class: check. Program will exit.

The source code is:

import java.io.*;
class check {

    public static void main (String [] args)
            {
            System.out.println("Hello");
            }
    }

Please try by set the class path first then compile and execute the class Then your problem will be resolved.

For example at command prompt:

C:\> setclasspath=%classpath%;.;
C:\> javac check.java
C:\> java check

Now, you will get the output as Hello.

You've got the CLASSPATH environment variable set, and it doesn't include . (dot), the current directory. Try this

java -cp . check

(That's java space dash cp space dot space check).
