How to add up many BigDecimals in Java
<p>I have this program in which I need to add up many BigDecimals. I have the following snippet of code</p>

<pre><code>BigDecimal Average = new BigDecimal(3.0);
BigDecimal ATT = new BigDecimal(0.0);
ATT.add(A_BigDecimal);
ATT.add(B_BigDecimal);
ATT.add(C_FullBigDecimal);
System.out.println("Total Amount: " + ATT); 
System.out.println("Average: " + ATT.divide(Average));
</code></pre>

<p>I keep getting errors everytime I try variants of this code, how do you add many BigDecimals together?
Edit: Forgot to mention that the output is zero, always zero, as if the reference variable isnt reading the add function. </p>
