Question

Provided below is my current code for sorting list of song objects using insertion sort. It doesn't seem to work however. Please help!!

public void sortSongsList() { //Sort songsList alphabetically String s = songsList.get(0).getName(); // s.compareTo() for (int i = 1; i < songsList.size(); i++) { for (int j = 1; j < songsList.size(); j++) { if (songsList.get(i).getName().compareTo(songsList.get(j).getName()) < 0) { Song t = songsList.get(j); Song s1 = songsList.get(j); Song s2 = songsList.get(j); s1 = songsList.get(j - 1); s2 = t; } } }

Explanation / Answer

public void sortSongsList() {
   
   int n=songsList.size();//get the length of list
    //performing insertion sort
    for (int j = 1; j < n; j++) {
       String s=songsList.get(j).getName();
       int i=j-1;
        while((i>-1) && (s.compareTo(songsList.get(i).getName())>0) {
            //songsList.replace(i+1,i); // for replace the songs in list (swapping songs)
           Song t=songsList.get(i-1);
           Song t1=songsList.get(i);
           songsList.replace(t,t1);
           i--;
       }
       Song t2=songsList.get(j);
       Song t3=songsList.get(i+1);
       songsList.replace(t3,t2);
   
    }
}
