What Causes ClassNotFoundException The classpath is a parameter that tells the JVM and the Java compiler where to look for user-defined classes and packages when running a program. When you use any of the following methods to load a class but the JVM can’t find it in the classpath, j...
When the JVM is unable to locate the main class, it’s often because it's looking for the corresponding.classfiles in the wrong classpath. Of course, the way to rectify this problem is to manually specify the classpath by either using packages or specifying the classpath. At this point,...
