Is it not possible to store BigDecimal values in a single-dimensional array

Question

My goal is store BigDecimal values as I input them through the Scanner class. I want to store BigDecimal numbers into an array so that I can sort them numerically. Can this be done using a single-dimensional array?

I can't find any BigInteger methods designed for this task. I want BigDecimal values because the decimal precision is important to me.

Would this not be an array containing BigDecimals? As such there would not need to be specific methods within BigDecimal to deal with this — Richard Tingle, Nov 16 '13 at 00:22
You're both right. This works: BigDecimal[] arrayValue = new BigDecimal[n]; I guess I forgot to include the array size. That confused me. Rookie mistake. — poetryrocksalot, Nov 16 '13 at 00:28

If you want to sort them easily, you could do the following:

    BigDecimal x1 = new BigDecimal("1235.2345");
    BigDecimal x2 = new BigDecimal("235.2345");
    BigDecimal[] nums = {x1,x2};
    List<BigDecimal> lnums = Arrays.asList(nums);
    Collections.sort(lnums);

Arrays.asList() merely passes the value of the reference of your array. Collections.sort() uses merge sort.

I hope this help you,

BigDecimal x = new BigDecimal(5.94839);
BigDecimal y = new BigDecimal(9.03937);
BigDecimal[] myBDArr = {x,y};
System.out.println(myBDArr[0]);
System.out.println(myBDArr[1]);

Output:

5.948389999999999844249032321386039257049560546875
9.0393699999999999050714905024506151676177978515625
