Question

JAVA: Provide a static method void append(ArrayList<T> a, ArrayList<T> b) that appends the elements of b to a.

HELP!

This is what I have:

import java.util.ArrayList;
public class ArrayListA
{
ArrayList<Sting> a = new ArrayList <string>();
a.add("apple");.add("banana");
b.add("carrot");
b.add("zucchini");
System.out.print("A Contents" + printMyList(a));
append(a, b);
System.out.println("A append" + printMyList(a));
}
public static printMyList(Array<String> myList)
{
String str = "";
for (String c : myList)
{ str = str + c + "";}
str = str + " ";
return str;
}
}

public static <T> void append(ArrayList<T> f, ArrayList<T> g)
{
for (T temp = g)
{ f.add(temp); }
}

Explanation / Answer

import java.util.ArrayList;

public class ArrayListA{
public static void main(String[] args){
ArrayList<String> a = new ArrayList <string>();
ArrayList<String> b = new ArrayList <string>();
a.add("apple"); a.add("banana");
b.add("carrot"); b.add("zucchini");
System.out.print("A Contents" + printMyList(a));
a = append(a, b);
System.out.println("A append" + printMyList(a));
}
public static void printMyList(ArrayList<String> myList){
String str = "";
for (String c : myList){
str = str + c + ' ';
}
return str;
}
public static ArrayList<String> append(ArrayList<String> f,ArrayList<String> g){
for (String temp : g){
f.add(temp)
}
return f;
}
}
