Get last Array

[osirion666]

int test = numbers.length;

    if (numbers[i] = test)
        {
    }

i want to find the last array in numbers then do something
with it for example out put it the above code is my attepmtp at it
however i am doingd something wrong and cant for the life of me figure out what it is.

Consider that numbers.length returns 5. That stands for

numbers[0]
numbers[1]
numbers[2]
numbers[3]
numbers[4]

Is this enough or you want other explanation?

int test = numbers.length;

if (numbers = test)

yeah you need to change the code, you don't need to loop over the array.

int test = numbers.length;
    
/*temporary variable with same type as numbers */  = numbers[test-1];

This will give you last member of the array to the temporary variable. Then do what you want to do with it.

Sorry i was not very clear in what my problem is for example i

i am currently reading the values of the array in a loop then
chaning a string based upon that
what i want to do is once it comes to the last element in the array
test =numbers.lenght i want it to do something specefic

for (int i = 0; i < numbers.length; i++)
{
    if (numbers.length >1)
        {
   replacement = replacement.append(numbers[i]+",");    // need to insert comma after number to send in bulk
   }
    else
replacement = replacement.append(numbers[i]+","); 

if (numbers[i] = int test)
{

  replacement = replacement.append(numbers[i]); 
    
        
    
    }
    // if only one number is seleceted then no comma is needed








    


}

Basically once it gets to the final array i dont want it to add a comma.
thanks for the help so far

Did you tried lastIndexOf() and deleteCharAt() of StringBuffer?

Try something like this :

int lastComma = replacement.lastIndexOf(",");
replacement.deleteCharAt(lastComma) ;

Hope this helps!

{
    if (numbers.length >1)
        {
   replacement = replacement.append(numbers[i]+",");    // need to insert comma after number to send in bulk
   }
    else
replacement = replacement.append(numbers[i]+","); 

if (numbers[i] = int test)
{

  replacement = replacement.append(numbers[i]);        
    
    }
    // if only one number is seleceted then no comma is needed  


}

Logic of the above for loop is completely of the hook
Can be done simply as

for (int i = 0; i < numbers.length; i++)
{
    if (i+1 == numbers.length){
        //DO SOMETHING SPECIAL LIKE PLACE A QUESTION MARK AT THE END
        replacement = replacement.append(numbers[i]+"?");
    }
    else{
        replacement = replacement.append(numbers[i]+",");    
   }
}

replace that code section in "if" statement with what ever you need to do at that point...
