Can't add to an ArrayList “misplaced construct(s)”

Question

I have a simple arraylist set up, but I can\'t seem to add objects to it.

import java.util.ArrayList;


public class Inventory {

ArrayList inventory = new A         


        

Answer 1

A more general answer would be that the class body is about declarations, not statements. There is special provision for statements occurring in class body, but they have to be marked explicitly as either class initializers or instance initializers. As the assignments are statements and statements are allowed only inside blocks of code(methods, constructors, static initializers, etc.). So you can do as below,

public class Inventory {

ArrayList inventory = new ArrayList();

String item1 = null;
String item2 = null;
String item3 = null;

//initializer block
{
item1="Sword";
item2="Potion";
item3="Shield";

inventory.add(item1);
inventory.add(item2);
inventory.add(item3);
}
