Returns the {@code Class} object associated with the class or interface with the given string name, using the default class loader.

The {@code name} can denote an array class (see Class#getName for details).

Returns the {@code Class} object associated with the class or interface with the given string name, using the given class loader.

The {@code name} can denote an array class (see Class#getName for details).

If the parameter {@code loader} is null, the class is loaded through the default class loader.

}

Returns the {@code Class} object associated with the class or interface with the given string name, using the default class loader.

The {@code name} can denote an array class (see Class#getName for details).

This method can be used to obtain any of the {@code Class} objects representing {@code void} or primitive Java types: {@code char}, {@code byte}, {@code short}, {@code int}, {@code long}, {@code float}, {@code double} and {@code boolean}.
