</div>

<div><br>
</div>
<div>My java is 11. </div>
<div>My scipoptsuite: 6.0.2.</div>
<div>My jscip cheked out from <a href="https://github.com/SCIP-Interfaces/JSCIPOpt" moz-do-not-send="true">https://github.com/SCIP-Interfaces/JSCIPOpt</a></div>
<div><br>
</div>
<div>I can run the example well. </div>
<div>e.g. <a href="https://github.com/SCIP-Interfaces/JSCIPOpt/blob/master/examples/Linear.java" moz-do-not-send="true">https://github.com/SCIP-Interfaces/JSCIPOpt/blob/master/examples/Linear.java</a></div>
<div><br>
</div>
<div>I have two questions:</div>
<div><br>
</div>
<div>(1) How can I print out the optimization model as .lp file ? </div>
<div><br>
</div>
<div>(2) How to set the optimization objective function ? </div>
<div><br>
</div>
<div>I cannot find how to do it from <a href="https://scip.zib.de/doc/html/PARAMETERS.php" moz-do-not-send="true">https://scip.zib.de/doc/html/PARAMETERS.php</a>. </div>
