Hi, I'm writing code in JAVA and trying to get solution time by using cplex.getTime. But I can not compile it, I got an error message as below;

/home/.../....java:364: cannot find symbol
symbol  : method getTime()
location: class ilog.cplex.IloCplex
        pw.println(" Solution time = " + cplex.getTime());
                                              ^
 
This is my code:

import ilog.concert.;
import ilog.cplex.;
import java.io.*;

....

if ( cplex.solve() ) {
   
    File outFile;
    PrintWriter pw;
        outFile = new File("output.txt");
        if (! outFile.exists()) {
  pw = new PrintWriter(new BufferedWriter(new FileWriter
(outFile)));
 
        pw.println(" Optimal Value = " + cplex.getObjValue());
       
        pw.println(" Solution time = " + cplex.getTime());
        pw.println(" Solution status = " +cplex.getStatus());

.....

}

Have anyone can help me to solve this problem? Do we have other commands to get the solution time?

Thanks!

In java, you might use Java system class to control times :

See
System.currentTimeMillis

Hope this helps,
