Explain the significance of class loaders in Bootstrap?

In order to load the Java Classes into a virtual environment, Classloader are used. A class loader will load key classes such as java.lang.object and several other codes into the memory. Usually, these classes are loaded only if a demand occurs. Since Java Runtime Environment includes loaders, they need not know about file and file systems. Also, the loaders are responsible for converting the named class into an equivalent binary form.
