I'm trying to replace some column values but i'm getting the error:
ORA-00911: invalid character
My query:
SELECT REPLACE (email, ‘.com’, ‘.net’) FROM emp;
How to resolve it?

Use public static void main(String[] args) {

FilePathUtils.addInputPath(path_Obj);
Mat bgrMat = matFactory.newMat(FilePathUtils.getInputFileFullPathList().get(0));
featOrientExe = Executors.newFixedThreadPool(1);
future0 = CompletableFuture.runAsync(new FeatOrientRun(bgrMat), featOrientExe);
CompletableFuture.allOf(future0).join();//blocks the main thread till future0, and future1 finishes
featOrientExe.shutdown();
Log.D(TAG, "MainClass", "SmoothedImgList:" + fo.getSmoothedImgList().size());
Log.D(TAG, "MainClass", "SubSampledImgList:" + fo.getSubSampledImgList().size());
for (int i = 0; i < fo.getSmoothedImgList().size(); i++) {
ImageUtils.showMat(fo.getSmoothedImgList().get(i), "SmoothedImgList_" + i);
}
for (int i = 0; i < fo.getSubSampledImgList().size(); i++) {
//Mat laplaceImg = SysUtils.applyLaplac(fo.getSubSampledImgList().get(i));
