java - Adding MouseListener to Graphics Object -


i'm struck in seems minor problem. tried add mouselistener line2d object it's not working. method or tried invalid or can way. me figure out i'm doing wrong here.

public class drawinglines {     public static void main(string[] args){         lineframe lf = new lineframe();         lf.setdefaultcloseoperation(jframe.exit_on_close);         lf.setvisible(true);      }    }  class lineframe extends jframe{     public lineframe(){         settitle("line test");         setsize(500, 500);         linespanel lp = new linespanel();         container contentpane = getcontentpane();         contentpane.add(lp);      } }  class linespanel extends jpanel{     public linespanel(){      }     public void paintcomponent(graphics g){       super.paintcomponent(g);       graphics2d g2 = (graphics2d)g;        line2d line = new line2d.double(105.5, 306.6, 350.8, 4.9);        g2.draw(line);        line.addmouselistener(new mouselistener(){           @override           public void mouseclicked(mouseevent e) {               system.out.println("line clicked !");           }            @override           public void mousepressed(mouseevent e) {           }            @override           public void mousereleased(mouseevent e) {           }            @override           public void mouseentered(mouseevent e) {           }            @override           public void mouseexited(mouseevent e) {           }         });          } }

add mouselistener linespanel. , use mouseevent coordinates check whether click close line.

see how select line

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
