ClassNotFound在Ubuntu终端中运行Java .class文件时出错

Question

I compile my file with javac myfile.java But when I run myfile.class file with command : java myfile I get an ClassNotFound error. My Java version is openjdk-6

Answer 1

Run the command as this (in the same directory where you compiled):

java -cp . myfile

Assuming of course that the file contains a class called myfile , which btw, doesn't follow standard Java naming practices (should begin with a capital letter).

Read up on here more about setting your runtime classpath.

Answer 2

Most likely your classpath is wrong. Try java -cp . myfile

Also, java tools tend to like javas normal conventions, so your class should be MyClass, and the file should then be MyClass.java
