Use the ResultsTable.getValue(heading, row) method to retrieve values from the results table.
imp = IJ.createImage("Testing Image", "8-bit White", 512, 512, 1);
or = new OvalRoi(10, 10, 12, 12);
imp.setRoi(or);
IJ.run(imp, "Measure", "");
rt = ResultsTable.getResultsTable();
IJ.log("area: "+rt.getValue("Area", 0));
IJ.log("mean: "+rt.getValue("Mean", 0));
Or simplify the code and avoid displaying the results table by using ImagePlus.getResults().
imp = IJ.createImage("Testing Image", "8-bit White", 512, 512, 1);
or = new OvalRoi(10, 10, 12, 12);
imp.setRoi(or);
stats = imp.getStatistics();
IJ.log("area: "+stats.area); IJ.log("mean: "+stats.mean);
