Integer to BigDecimal

hi guys
i have something like this in my value object CriteriaVO

private Object values[] = null;
public Object[] getValues() {
            return values;
      }

public void setValues(Object[] values) {
            this.values = values;

            for (int i=0; values!=null && i<values.length; i++){
                  if (values[i] !=null && values[i] instanceof String)
                        this.values[i] = ((String)values[i]).toUpperCase();
            }

      }

AND i have a method like this which uses the value object:

private static Search modify(CriteriaVO criteria[] )
for (int j = 0; j < criteria.length; j++)
{
if((!criteria[j].getValues().equals(Plan.getPeak()))) //this is not matching
}

//criteria[j].getValues() is 1000
and Plan.getPeak() is of type Big integer and its value is 1000.00

so i want to convert criteria[j].getValues() (which is 1000) to Bigdecimal so that the values match.

any idea how i can do that
thanks

The getValues you've shown returns an array, so how can it be 1000?

Or BigDecimal - whichever

Mick Barry

this.values[i] = new BigInteger((String)values[i]);

CEHJ

Assuming when an Object is String it's not a number (else why convert it to uppercase)

if (values[i] !=null && values[i] instanceof String) {
// whatever
}
else if (values[i] !=null && values[i] instanceof Number) {
BigDecimal bi = new BigDecimal(values[i].toString());
}

is this correct
(!BigInteger((String)values[i]).equals(pricePlan.getPeakAllowanceMinutes()))

it shows an error:
It says method BigInteger is undefined for Type Plan class

my if statement is
if(!BigInteger((String)values[i]).equals(pricePlan.getPeakAllowanceMinutes()))

If the String types in the array contain numbers, why are you converting to uppercase?:

>>this.values[i] = ((String)values[i]).toUpperCase();

it could be anything , numbers or alphabets

Mick Barry

> it could be anything , numbers or alphabets

then you'll need to add a try/catch block around what i suggested above to habdle cases where it is not a number (unless you have some other way of telling)
Or first check if it numberic or not?

you can do that with a regular expression

or loop thru the chars checking the digits (preferred)

let me know if u have any questions
