6 This details is critical and justifies an express mention (this is the only response that mentions extends). I've just discovered the hard way that when most important class fails to load mainly because it extends One more that can not be located, java isn't going to report which real course wasn't identified (unlike NoClassDefFoundError). So Of course it does come about, and it's a hair-pulling predicament when you do not know this.
Computer system power consumption is effectively beneath 400W, even with large-close components. Modern day PCs Specially have very low power demands– my very own Laptop at max load should not ever exceed 310 Watts, for instance.
In which this UPS will turn out to be useful is as a unit for reduced-power PCs and consoles. Several prebuilt HTPCs and Office environment PCs, for instance, will have A lot decrease wattages in comparison to the 390W focus on needed by this unit.
So ... if you have specified the class name properly, the next factor to check is that you have specified the classpath appropriately:

Although UPS systems DO offer you SOME defense in the shape of (Normally) MOVs, they don't seem to be primarily "protection" devices. There are many exceptions not surprisingly but Those people are generally A great deal bigger end models that are not in any way low cost.

Nonetheless, it might trigger damage in more complex devices that operate instantly off AC power and count at stake voltage, which include:
However it continues to be probable for this exception to occur, if you need to do factors guiding the again from the IDE. As an example, if you have Earlier arrange an Application Launcher for the เครื่องสํารองไฟ ขึ้นสีแดง Java app in Eclipse, and also you then moved the JAR file containing the "primary" class to a different place in the file system devoid of telling Eclipse
