66-81: Add n==0 base case to pow method
Without it, pow(0) recurses infinitely—before then==1check, return a new identity matrix (1s on diagonal, 0s elsewhere) for n==0.
28-35: Off-by-one in Fibonacci outputs.Mⁿ = [[F(n+1), F(n)], [F(n), F(n-1)]] so
•temp[1][1] = F(i-1),temp[1][0] = F(i),temp[0][0] = F(i+1)
Current code prints F(i-1), F(i), F(i+1) but the loop intends F(i), F(i+1), F(i+2).
Fix:- if (i <= size) - out.println(temp[1][1]); - if (i + 1 <= size) - out.println(temp[1][0]); - if (i + 2 <= size) - out.println(temp[0][0]); + if (i <= size) + out.println(temp[1][0]); // F(i) + if (i + 1 <= size) + out.println(temp[0][0]); // F(i+1) + if (i + 2 <= size) + out.println(temp[0][0].add(temp[1][0])); // F(i+2)Confirm intended indexing (0- or 1-based).
🧹 Nitpick comments (4)
src/main/java/com/emc/test/fibonacci/FibonacciCoreCalucaltion.java (4)
1-3: Javadoc added — consider brief class description and license header.Nice to have: add a 1–2 line summary of what this class does and, if applicable, a license header.
13-16: Class name is misspelled; consider renaming to FibonacciCoreCalculation.Current name: FibonacciCoreCalucaltion. Renaming improves clarity and discoverability. This is a breaking change (file/class rename and references). Consider a follow‑up PR.
20-23: Use BigInteger constants instead of string parsing.Replace new BigInteger("1"/"0") with BigInteger.ONE/BigInteger.ZERO for clarity and performance.
Apply:
- matrix[0][0] = new BigInteger("1"); - matrix[0][1] = new BigInteger("1"); - matrix[1][0] = new BigInteger("1"); - matrix[1][1] = new BigInteger("0"); + matrix[0][0] = BigInteger.ONE; + matrix[0][1] = BigInteger.ONE; + matrix[1][0] = BigInteger.ONE; + matrix[1][1] = BigInteger.ZERO;
25-43: Prefer try‑with‑resources and explicit UTF‑8 encoding when writing files.Avoids resource leaks and platform‑dependent encodings.
Apply:
- PrintWriter out = null; - try { - out = new PrintWriter(new FileOutputStream(fileName)); + try (PrintWriter out = new PrintWriter( + fileName, + java.nio.charset.StandardCharsets.UTF_8.name())) { for (int i = startNum; i <= size; i = i + 3) { temp = pow(i); if (i <= size) out.println(temp[1][1]); if (i + 1 <= size) out.println(temp[1][0]); if (i + 2 <= size) out.println(temp[0][0]); } - } catch (Exception e) { + } catch (Exception e) { LOGGER.error(e.getMessage(), e); - } finally { - if (out != null) { - out.close(); - } - } + }
