Thread: How do I return an array list?

All you have to do is go through the list and System.out.println each one, which is how i used to do it long ago, but most of the time these days i find myself watching things in the debugger

If you don't know how to go through each element in your array list, look up the iterator class

public ArrayList/*<type>*/ methodName(/* parameters */)
	{
		ArrayList arraylist = new ArrayList();
		/**
		 * code here
		 */
 
		return arraylist;
	}
 
	/**
	 * or
	 */
 
	public ArrayList arrayList = new ArrayList();
 
 
	public ArrayList/*<type>*/ method2Name(/* parameters */)
	{
		return arrayList;
	}

You should read up on returning something. If you are using a method, the second word typed is what is returned. Void means it returns nothing, boolean means you have to return a boolean. int means you have to return an int and so on. It can be done with any object you create. Try experimenting with methods that return something. For instance, in ArrayList, the size() method returns an int of how long the ArrayList is.

public void name(String name){System.out.println(name);}
 
//could be
 
public String name(String name)
{
    return name;
}

What is returned is completely up to you and the purposes of the method you are writing.
