Command line stuff

Question

For some reason I can't get my program to run with the command line. It says that it can't find the main method, but when I run it in JCreator it works perfectly.
I set the path to "C:\Program Files\Java\jdk1.5.0_05\bin"
Then I went to the directory of the .class file.
Then I typed java Pong
What am I missing?

Answer 1

Path is irrelevant for finding classes. That only matters for finding java.exe.
Classpath is for finding classes. (Your IDE probably has its own settings, rather than the classpath envrionment variable or -cp command line options.)

java -cp .;<any other directories or jars> YourClassNameYou get a NoClassDefFoundError message because the JVM (Java Virtual Machine) can't find your class. The way to remedy this is to ensure that your class is included in the classpath. The example assumes that you are in the same directory as the class you're trying to run.
javac -classpath .;<any additional jar files or directories> YourClassName.javaYou get a "cannot resolve symbol" message because the compiler can't find your class. The way to remedy this is to ensure that your class is included in the classpath. The example assumes that you are in the same directory as the class you're trying to run.
