public short getMajorVersion() {
		return majorVersion;
	}
Returns the major version number of this class.
<p>
If a class file has major version number M and minor 
version number m, we denote the version of its
class file format as M.m. Thus, class file format versions may be ordered
lexicographically, for example, 1.5 < 2.0 < 2.1.
<p>
A Java virtual machine implementation can support a class file format of
version v if and only if v lies in some contiguous range Mi.0 ? v ? Mj.m.

@return the major version number of this class.
