1. Create a wrapper class with elements
1. name :String
2. code :String
3. price :Decimal
Solution :
----------
public class ProdWrapper {
public String name {set;get;}
public String code {set;get;}
public Decimal price{set;get;}
}
2. Create a class ProductList with following members
1.products :List<ProdWrapper> // This will contain the intial list of product that we want to display
2.myList : List<ProdWrapper> // This will contain the list
prodWrapper elements whose
name is not null
3. ProductList() : Assign the memory for Products and
add two prodWrapper elements to the list
4. addMore(): void : When ever this method is called add two
prodWrapper elements to the list
Snippet :
public void addMore(){
for(Integer i=1;i<=2;i++){
ProdWrapper pw=new ProdWrapper();
products.add(pw);
}
}
5: clearAll() :void : When this method is called remove all the
elements from the products list
Snippet:
public void clearAll(){
products.clear();
}
6: submit() : When call this methods all the ProdWrapper elements from product list whose name is not null put those prodWrpper elements into mylist
Snippet :
public void submit(){
myList=new List<ProdWrapper>();
for(ProdWrapper p:Products){
if(p.name!=null && p.name!=''){
mylist.add(p);
}
}
}
Complete Class :
==================
public class ProductList {
public List<ProdWrapper> products {Set;get;}
public List<ProdWrapper> myList {Set;get;}
public ProductList(){
products=new List<ProdWrapper>();
addMore();
}
public void addMore(){
for(Integer i=1;i<=2;i++){
ProdWrapper pw=new ProdWrapper();
products.add(pw);
}
}
public void clearAll(){
products.clear();
}
public void submit(){
myList=new List<ProdWrapper>();
for(ProdWrapper p:Products){
if(p.name!=null && p.name!=''){
mylist.add(p);
