Public boolean remove(Grocery ent)

Question

I have an arraylist
Arraylist <Grocery> = shoppingList;

How would I search in the shoppingList, if found ent in the list remove it, set value to found

How would i do this in this method

Public boolean remove(Grocery ent) {
Boolean found = true;

Return found;

}

Answer 1

try if/else like if „ent“ contains in shoppingList then set found true
and if found is true Remove ent

u can also add a boolean deleted so after u deleted ent u can set deleted true and returned then

Answer 2

can someone show a sample code of how i should do it?

Answer 3

ArrayList<Grocery> g=new ArraryList<>();
g.add(ent);
g.add(ent2); //for adding to List

public boolean remove(Grocery ent)
{
If( g.contains(ent) )
{
g.remove(ent); //for removing
return true;
}
else
return false;

//A sample only, not complete ....
