one example error is

"error: cannot find symbol points.add( new Point2D(lineX + t*lineY, lineY - t*lineX) );" - cannot find Point2D..

i already set the classpath to DDogleg jar. files

Dear Mohd,

If you go to the following link:

https://github.com/lessthanoptimal/ddogleg/tree/v0.14/examples/src/org/ddogleg/example

you will find the "Point2D.java" file that will define the class you are missing for your compilation.
