Method Detail

findClass

public static java.lang.Class findClass(java.lang.String arg)

Return an instance of a Class that corresponds to the specified class name. This is juat a wrapper around Class.forName, but catches the exception that gets thrown if the name is invalid, and prints an error. This way, applications that are quite sure there will not be an error don't have to catch the exception themselves.
