# using a count method.

I have created the folowing method to analyse the results of the lottery machines,  however the count is always 0, the vector is created correctly and I can create the table but the value of times used is alway 0 for the 12 machines, table has 12 rows , which is correct with the different machine name.

Whats wrong with this algorithm? I think its not running the if statement to add on 1 to the count correct?

public static void createMResults(){
row = 0;
column = 9;
machineCount = 0;
machine = new Vector();
rowCount = table.getRowCount();

do{
count = 0;
row = 0;
machineCount++;
try{
if (machineCount == 1){
strMachine = "AMETHYST";}
else if (machineCount == 2){
strMachine = "MOONSTONE";}
else if (machineCount == 3){
strMachine = "OPAL";}
else if (machineCount == 4){
strMachine = "TOPAZ";}
else if (machineCount == 5){
strMachine = "GARNET";}
else if (machineCount == 6){
strMachine = "PEARL";}
else if (machineCount == 7){
strMachine = "LANCELOT";}
else if (machineCount == 8){
strMachine = "ARTHUR";}
else if (machineCount == 9){
else if (machineCount == 10){
strMachine = "GUINEVERE";}
else if (machineCount == 11){
strMachine = "MERLIN";}
else if (machineCount == 12){
strMachine = "VYVYAN";}
do{
try{
tableValue = table.getValueAt(row,column);
strMachineTV = tableValue.toString();
if (strMachineTV.equals(strMachine)){
count++;
row++;
}
else{
row++;
}
}
catch (NullPointerException e) {
row++;
}
catch (ArrayIndexOutOfBoundsException e) {
row++;
}
}while (row <= 0);
//problem here!! out of bounds exception
Vector machineSet = new Vector();
}
catch (NullPointerException e) {
}
catch (ArrayIndexOutOfBoundsException e) {
}
}while (machineCount <= 11);
}

i know

}while (row <= 0);

should be

}while (row <= rowCount);

just changed it for testing

it should be      while ( row <= rowCount-1 ) ; isn't it.

The reason is java is zero based index system.

if (strMachineTV.equals(strMachine)){
count++;
row++;
}

that works fine the problem is here, I have used system.out.println and is just not rcognising when the equal or I am resetting cout to soon??

Firstly try changing

>>strMachineTV = tableValue.toString();

to

strMachineTV = tableValue.toString().trim();
