`static java.lang.String`	`getPackageName(java.lang.String className)`	Gets the package name of the given class name.
`static java.lang.String`	`getQualifiedFileName(java.lang.String fileName, java.lang.String packageName)`	Qualifies the given `fileName` with the given `packageName` and returns the resulting file path. If `packageName` is `null` or a zero-length String, this method will return `fileName`.
`static java.lang.Class`	`loadClass(java.lang.ClassLoader classLoader, java.lang.String className)`	Capsulates the ClassLoader.loadClass method to throw no exceptions but return null instead.
