Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 101

I am trying to see the contents of an array, but when I run it comes an error message

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 101

Does anyone know where the problem is? here is my code:

public final class KonversiQtoH extends DebitDiberikan{

public KonversiQtoH() throws SQLException{
    QBeriPintu1();
}
Connection c = KoneksiDatabase.getKoneksi();
Float[] fine;
public void QBeriPintu1() throws SQLException{
    try{
        List rowValues = new ArrayList();
        Statement s = c.createStatement();
        String sql = "SELECT LA40 from tabel_debit";
        ResultSet rs = s.executeQuery(sql);
        while (rs.next()){
            rowValues.add(rs.getFloat("LA40"));
        }
        rs.close();
        s.close();
        fine = (Float[]) rowValues.toArray(new Float[rowValues.size()]);
    }catch(SQLException e){
        System.err.println("QKanan, error");
    }
}
public static void main(String[] args) throws SQLException{
    KonversiQtoH j = new KonversiQtoH();
    j.QBeriPintu1();
    for (int i=0; i<=j.fine.length; i++){
        int a = i+1;
        System.out.println(a+". "+j.fine[i]);
    }
}
}

You should remove the "=" i<=j.fine.length

for (int i=0; i<j.fine.length; i++){
    int a = i+1;
    System.out.println(a+". "+j.fine[i]);
}

The following line produces errors:

for (int i=0; i<=j.fine.length; i++) {

Replace with:

for (int i=0; i<j.fine.length; i++) {

Change here 

for (int i=0; i<=j.fine.length; i++){
        int a = i+1;
        System.out.println(a+". "+j.fine[i]);
    }

to

for (int i=0; i<j.fine.length; i++){
        int a = i+1;
        System.out.println(a+". "+j.fine[i]);
    }

Comparison operatore from <= to <

This appears to be the problematical code:

for (int i=0; i <= j.fine.length; i++) {
    int a = i+1;
    System.out.println(a+". "+j.fine[i]);
}

Arrays in Java are indexed from zero to the length minus one. The above loop actually tries to access one beyond the length of the array. Fixing the bounds should get rid of this error:

for (int i=0; i < j.fine.length; i++){
    int a = i+1;
    System.out.println(a+". "+j.fine[i]);
}
