BigDecimal[] val = {0,0,0};

BigDecimal[] val = new BigDecimal[N];
Arrays.fill(val, BigDecimal.ZERO);

BigDecimal[] val = { BigDecimal.ZERO,
                    BigDecimal.ZERO,
                    BigDecimal.ZERO };

BigDecimal[] val = {new BigDecimal(0),new BigDecimal(0),new BigDecimal(0)};

BigDecimal val = 0;  // Fails
BigDecimal val = new BigDecimal(0);  // Succeeds

BigDecimal[] val = new BigDecimal[10]; // 10 for example - chosse the size you want
 Arrays.fill(val, BigDecimal.ZERO);

Like this you can pass the BigDecimal Value:

BigDecimal amt = null;

amt = new BigDecimal("110000");
