Typically, it is stored in the manifest that is 0N/A * distributed with the classes. 0N/A * <p>The set of classes that make up the package may implement a 0N/A * particular specification and if so the specification title, version number, 0N/A * and vendor strings identify that specification. 0N/A * An application can ask if the package is 0N/A * compatible with a particular version, see the {@link 0N/A * #isCompatibleWith isCompatibleWith} 0N/A * method for details. 0N/A * <p>Specification version numbers use a syntax that consists of nonnegative 0N/A * decimal integers separated by periods ".", for example "2.0" or 0N/A * "1.2.3.4.5.6.7". This allows an extensible number to be used to represent 0N/A * major, minor, micro, etc. versions. The version specification is described 0N/A * by the following formal grammar: 0N/A * <dt><i>SpecificationVersion: 0N/A * <dd>Digits RefinedVersion<sub>opt</sub></i> 0N/A * <p><dt><i>RefinedVersion:</i> 0N/A * <dd>{@code .} <i>Digits</i> 0N/A * <dd>{@code .} <i>Digits RefinedVersion</i> 0N/A * <p><dt><i>Digit:</i> 0N/A * <dd>any character for which {@link Character#isDigit} returns {@code true}, 0N/A * <p>The implementation title, version, and vendor strings identify an 0N/A * implementation and are made available conveniently to enable accurate 0N/A * reporting of the packages involved when a problem occurs. The contents 0N/A * all three implementation strings are vendor specific. The 0N/A * implementation version strings have no specified syntax and should 0N/A * only be compared for equality with desired version identifiers. 0N/A * <p>Within each {@code ClassLoader} instance all classes from the same 0N/A * java package have the same Package object.
