### Question:
NumberAlgorithm { public static Integer getPrimeNumberSum(int start, int end) { int rs = 0; for (Integer p : getPrimeNumbers(start, end)) { rs += p; } return rs; }  static List<Integer> getPrimeNumbers(int start, int end); static Integer getPrimeNumberSum(int start, int end); static void output(int[][] num, int start, int end);  }### Answer:
@Test public void testGetPrimeNumberSum() { System.out.println(NumberAlgorithm.getPrimeNumberSum(1, 100)); }
