swing - how to return to first cell in the column after editing the last cell in column in java? -

-

i have created table have 5 columns. cells in column 2 , 3 editable. column 2 has default jtextfield editor , should take number(0,1,2,3,...,9) value only. when application loaded first time, automatically first cell in column 2 become selected , table focus below.

public void initfocus(){     swingutilities.invokelater(new runnable()      {         public void run() {            itemstable.changeselection(0,2,false,false);            itemstable.requestfocusinwindow();         }     }); }

what want achieve below:

  1. by pressing number(0 until 9) cell edited new value.
  2. by pressing enter next cell in column ready edited.
  3. if user riches last cell in column , edit , press enter, first cell in column ready editing again.

i have tried in table result not ok: body know how catch these goals? example of simple table appreciated. in advance

itemstablemodel = new defaulttablemodel(){             @override             public boolean iscelleditable(int row, int column) {                 return column == 2 || column==3;             }         }; itemstablemodel.setcolumnidentifiers(new object[]{"product", "itemcode","qty","date", "productid"});  itemstable = new jtable(itemstablemodel){        public void changeselection(int row, int column, boolean toggle, boolean extend)        {                 super.changeselection(row, column, toggle, extend);                 if(column==2 && row != -1)                 {                      if (editcellat(row, column))                     {                         component editor = geteditorcomponent();                         editor.requestfocusinwindow();                         ((jtextcomponent)editor).selectall();                     }                      if(isediting() && row == itemstable.getrowcount()-1)                      {                         super.changeselection(0, 2, toggle, extend);                         component component = itemstable.getcelleditor(0,2).gettablecelleditorcomponent(itemstable,getvalueat(row, column),true,row,column);                         component.requestfocusinwindow();                         ((webtextfield)component).selectall();                     }                  }        }   }; itemstable.setdefaultrenderer(object.class, retrieveitemstablecellrenderer()); itemstable.setcellselectionenabled(true);

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
