<DL>
<DD>Determines the <code>long</code> value of the system property
 with the specified name.
 <p>
 The first argument is treated as the name of a system property. 
 System properties are accessible through the 
 <A HREF="../../java/lang/System.html#getProperty(java.lang.String)"><CODE>System.getProperty(java.lang.String)</CODE></A> method. The 
 string value of this property is then interpreted as a long value 
 and a <code>Long</code> object representing this value is returned. 
 Details of possible numeric formats can be found with the 
 definition of <code>getProperty</code>. 
 <p>
 If there is no property with the specified name, if the specified name
 is empty or null, or if the property does not have the correct numeric
 format, then <code>null</code> is returned.
 <p>
 In other words, this method returns a <tt>Long</tt> object equal to 
 the value of:
 <blockquote><pre>
 getLong(nm, null)
 </pre></blockquote><DD><DL>
</DL>
</DD>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>nm</CODE> - property name.<DT><B>Returns:</B><DD>the <code>Long</code> value of the property.<DT><B>See Also: </B><DD><A HREF="../../java/lang/System.html#getProperty(java.lang.String)"><CODE>System.getProperty(java.lang.String)</CODE></A>,

<DL>
<DD>Determines the <code>long</code> value of the system property
 with the specified name.
 <p>
 The first argument is treated as the name of a system property. 
 System properties are accessible through the 
 <A HREF="../../java/lang/System.html#getProperty(java.lang.String)"><CODE>System.getProperty(java.lang.String)</CODE></A> method. The 
 string value of this property is then interpreted as a long value 
 and a <code>Long</code> object representing this value is returned. 
 Details of possible numeric formats can be found with the 
 definition of <code>getProperty</code>. 
 <p>
 The second argument is the default value. A <code>Long</code> object
 that represents the value of the second argument is returned if there
 is no property of the specified name, if the property does not have
 the correct numeric format, or if the specified name is empty or null.
 <p>
 In other words, this method returns a <tt>Long</tt> object equal 
 to the value of:
 <blockquote><pre>
 getLong(nm, new Long(val))
 </pre></blockquote>
 but in practice it may be implemented in a manner such as: 
 <blockquote><pre>
 Long result = getLong(nm, null);
 return (result == null) ? new Long(val) : result;
 </pre></blockquote>
 to avoid the unnecessary allocation of a <tt>Long</tt> object when 
 the default value is not needed.<DD><DL>
</DL>
</DD>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>nm</CODE> - property name.<DD><CODE>val</CODE> - default value.<DT><B>Returns:</B><DD>the <code>Long</code> value of the property.<DT><B>See Also: </B><DD><A HREF="../../java/lang/System.html#getProperty(java.lang.String)"><CODE>System.getProperty(java.lang.String)</CODE></A>,

<DL>
<DD>Returns the long value of the system property with the specified
 name.  The first argument is treated as the name of a system property.
 System properties are accessible through the 
 <A HREF="../../java/lang/System.html#getProperty(java.lang.String)"><CODE>System.getProperty(java.lang.String)</CODE></A> method. 
 The string value of this property is then interpreted as a long 
 value, as per the <code>Long.decode</code> method, and a 
 <code>Long</code> object representing this value is returned.
 <p><ul>
 <li>If the property value begins with the two ASCII characters
 <tt>0x</tt> or the ASCII character <tt>#</tt>, not followed by a 
 minus sign, then the rest of it is parsed as a hexadecimal integer
 exactly as for the method <A HREF="../../java/lang/Long.html#valueOf(java.lang.String, int)"><CODE>valueOf(java.lang.String, int)</CODE></A> 
 with radix 16. 
 <li>If the property value begins with the character <tt>0</tt> followed
 by another character, it is parsed as an octal integer exactly
 as for the method <A HREF="../../java/lang/Long.html#valueOf(java.lang.String, int)"><CODE>valueOf(java.lang.String, int)</CODE></A> with radix 8. 
 <li>Otherwise the property value is parsed as a decimal
 integer exactly as for the method 
 <A HREF="../../java/lang/Long.html#valueOf(java.lang.String, int)"><CODE>valueOf(java.lang.String, int)</CODE></A> with radix 10. 
 </ul>
 <p>
 Note that, in every case, neither <tt>L</tt> nor <tt>l</tt> is 
 permitted to appear at the end of the property value as a type 
 indicator, as would be permitted in Java programming language 
 source code.
 <p>
 The second argument is the default value. The default value is
 returned if there is no property of the specified name, if the
 property does not have the correct numeric format, or if the
 specified name is empty or null.<DD><DL>
