    selection sort & insertion sort sort methods? - java

    I have been working on the code for an alpha sort file and have become stumped. I need to incorporate both an insertion sort & selection sort method into my code before it will run.

    I attached the file I have been working on and it runs on Bluej with Java JDK. I would apretiate if you could take a look at it. If you would prefer not to download my file I have posted my code that I have been working on below.

    I am not familiar with the structure of an insertion sort or a selection sort mothod. I also am not clear on the point in which these methods would need to be placed in the file.

    import java.io.*;
    import java.util.*;
    public class Words
    ArrayList<String> words;
    public Words()
    words = getData("wordlist.txt");
    public void displayWords()
    for(int i=0; i<words.size(); i++) {
    public ArrayList<String> getData(String filename)
    ArrayList<String> list = new ArrayList<String>();
    File myFile = new File(filename);
    if(myFile.exists() && myFile.length()>0) {
    try {
    BufferedReader in = new BufferedReader( new FileReader(myFile) );
    String word = in.readLine();
    while( word != null ) {
    word = in.readLine();
    } catch( Exception e )
    return list;

    This is the JavaSCRIPT forum.

    Your question is about JAVA.

    About the only thing the two languages have in common are the letters J-A-V-A at the start of their names.

    By the way: Google is your friend. Clearly this is homework, so try googling for how the two kinds of sorts work.

    A realist drinks it no matter how much there is.
