how Java find and loads the classes, that's a little bit complex topic for beginners, but we will touch the same base java error could not find or load main class netbeans here. For the curious reader, I would suggest reading my post How Classpath works in Java, a must read for a beginner. For now, you just remember that there is an environment variable called CLASSPATH http://stackoverflow.com/questions/18093928/what-does-could-not-find-or-load-main-class-mean which includes directories where Java looks for all class files and if it doesn't find your main class there then it throws "Error: Could not find or load main class XXX", where XXX is the name of your main class. Since many Java programmer is now started programming using Eclipse they face this issue when they first try to run their Java program from command line. In Eclipse, it's easy to compile http://javarevisited.blogspot.com/2015/04/error-could-not-find-or-load-main-class-helloworld-java.html and run the program because Eclipse takes care of all Classpath setup, but when you run your Java program from command line, CLASSPATH environment variable comes in picture. Personally, I don't like this environment variable and doesn't define in my environment variable, because its confusing and source of so many classpath related issue. Instead, I use -cp or -classpath option with java command to run my program. This way you always know which JARs are included in your classpath. For beginners, another important thing to understand is the difference between PATH and CLASSPATH, you must know that PATH is used locate system executable, commands or .exe, .dll files (in Windows) and .so files (in Linux). It is also used to locate native libraries used by your Java program. While, CLASSPATH is used to locate the class file or JAR files. It's Java class loader who looked into CLASSPATH for loading classes. Coming back to the problem in hand, if you are a beginner in Java, who are able to run the program from Eclipse but getting "Error: Could not find or load main class HelloWorld" when trying to run the same program from the command line then follow the steps given here to solve it.

This Site Careers Other all forums Forum: Beginning Java Java problem: Could not find or load class bolisetti sriharsha Greenhorn Posts: 8 posted 5 years ago I am new to java but previously i did some basic programs on my system.... i never got this error message....so i removed java sdk and reinstalled it... i set PATH variable as C:\Program Files\Java\jdk1.7.0\bin CLASSPATH variable as C:\Program Files\Java\jdk1.7.0\lib JAVA_HOME as C:\Program Files\Java\jdk1.7.0 i am unable to run even programs which i executed earlier... when i compile them ... it is not showing any error message but when i tried to run them(by using java command in command prompt) iam getting error message as "Error: Could not find or load main class Applicant" PLZZZZ Help me Guys........... sorry for my poor english THANKS IN ADVANCE Ganesh Akondi Greenhorn Posts: 6 I like... posted 5 years ago 2 To check whether JDK got installed properly or not..open command prompt and type javac ->enter You should get some list of options instead of an error message like javac is not an internal command. Then you have installed your JDK properly. Differences between PATH and CLASSPATH is: (both are environmental variables) PATH - points to bin of your java installation (system variable to tell the OS where is your JDK installed) CLASSPATH - can say java variable, which is used to tell locations of all jar/zip(classes) files to Compiler. Classpath is nothing but setting up the environment for Java. Java will use to find compiled classes eg: If we are using JDBC Driver then we need to keep classes12.jar in classpath, If we are using sevlets future then we need to keep servlet-api.jar in classpath .. like these so many places we use this. bolisetti sriharsha Greenhorn Posts: 8 posted 5 years ago Thanks for the reply..... when i typed javac and pressed enter.... it shows ..as you said a list of options.... so jdk is installed properly..
