[FIXED] Bubble.sort Ranking from Lowest to Highest() Java

Issue

Good evening guys! I'm doing the course homework and the teacher gave us an exercise in which we need to sort the Ranking. He orders the first 5 positions, we are in this impasse almost a week :(

Below follows the code:

for (int i = 1; i < valores.size (); i++) {
for (int k = i + 1; k < valores.size ()  -  1; k++) {
    if ((valores.get ( i )).compareTo ( valores.get ( k ) ) > 0) {
        Double temp1 = valores.get ( i );
        valores.set ( i, valores.get ( k ) );
        valores.set ( k, temp1 );
        Ouvinte temp = listaSorteio.get ( i );
        listaSorteio.set ( i, listaSorteio.get ( k ) );
        listaSorteio.set ( k, temp );
    }
}
System.out.println ( (i) + " - Valores: " + valores.get ( i ) + "\t\tPessoa: " + listaSorteio.get ( i ));

}

Solution

Why do you do

for (int i = 1; i < valores.size (); i++) 

? The error come from that

Always remember that in an array the indice begin by 0 and finish by the length of the array-1...

for (int i = 0; i < valores.size (); i++) {}
