    Default Help with my code please!

    Every time I compile this program, it always says there's an error, and I feel like I've done everything right. Currently it's saying that "sentence.add(str1);" has an error because it can't find a symbol? And also the project says that this program should be using the String Class but it wants us to list the words in an Arraylist. When I used the String Class first, it couldn't compile because I wasn't using an Arraylist Class even though I used an Arraylist. So how can we even use it in a String Class if there's an Arraylist? HELP, please.

    Here is the code:

    class Arraylist{
    public static void main(String [] args){
    Arraylist sentence = new Arraylist();
    String str1 = "Finally";
    String str2 = "the";
    String str3 = "weather";
    String str4 = "is";
    String str5 = "warm!";
    sentence.add(str1);
    sentence.add(str2);
    sentence.add(str3);
    sentence.add(str4);
    sentence.add(str5);
    System.out.println(sentence);
    }
    }

    Please copy the full text of the compiler's error messages and post it here.

    Please edit your post and wrap your code with code tags:
    [code=java]
    <YOUR CODE HERE>
    [/code]

    Your problem here is that you are creating your own arraylist object. Is there a reason you are not using the ArrayList class from the java.util package?

    Here are the directions to my assignment:

    Write two programs: one using the String class and one using the StringBuffer class. Your programs should store a set of Strings in an ArrayList and print those Strings in the order by which they are added. The output of your programs should create a complete sentence.

    Am I completely off base with my code? I am new to Java and I appreciate all the help

    One problem with the code (as Chris said) is the use of a name (Arraylist) that is very similar to a java SE class: ArrayList.

    If you are getting errors, post the full text here.

    I think the issue you are having is that you did not realize that ArrayList is a class that already exists. Head over to google and look it up. It's a great class that you will use for years to come, might as well get acquainted with it.

    Thank you all so much for the advice! I have made a few changes and I am still receiving errors. Here is the updated copy of my code. Any ideas?

    class test{
    public static void main(String [] args){
    sentence = new Arraylist();
    String str1 = "Finally";
    String str2 = "the";
    String str3 = "weather";
    String str4 = "is";
    String str5 = "warm!";
    sentence.add(str1);
    sentence.add(str2);
    sentence.add(str3);
    sentence.add(str4);
    sentence.add(str5);
    System.out.println(sentence);
    }
    }
