In Linux, Error: cocould not find or load main class Hello

In linux, I wrote a very simple Hello world Program. When compiling and running the program, an Error occurs: Error: cocould not find or load main class Hello.

The CLASSPATH problem was found at last.

First, check whether the jdk environment variables are correctly configured. Refer to this article: ubuntu12.04 install and configure jdk1.7.

Mainly in the environment variable:

Export JAVA_HOME =/usr/java/jdk1.8.0export JRE_HOME =$ {JAVA_HOME}/jre export CLASSPATH =.: $ {JAVA_HOME}/lib :$ {JRE_HOME}/lib export PATH =$ {JAVA_HOME}/bin: $ PATH

My environment variables are configured incorrectly. After the modification, the source/etc/profile file will be reloaded. OK, no error will be reported now!
