### Question:
Version { public boolean greaterOrEqualThan(Version version) { for (int i = 0; i < numbers.length; i++) { if (numbers[i] > version.numbers[i]) return true; if (numbers[i] < version.numbers[i]) return false; } return true; } Version(String version); boolean greaterOrEqualThan(Version version); String toString();  }### Answer:
@Test public void testGreaterOrEqualThan() { Version requiredVersion = new Version("1.6.0.10"); Version version15 = new Version("1.5.0.0"); Version lesserVersion = new Version("1.6.0.0"); Version equalVersion = new Version("1.6.0.10"); Version version1620 = new Version("1.6.0.20"); Version greaterVersion = new Version("1.7.0.0"); assertFalse(version15.greaterOrEqualThan(requiredVersion)); assertFalse(lesserVersion.greaterOrEqualThan(requiredVersion)); assertFalse(new Version("1.5.0.20").greaterOrEqualThan(requiredVersion)); assertTrue(equalVersion.greaterOrEqualThan(requiredVersion)); assertTrue(version1620.greaterOrEqualThan(requiredVersion)); assertTrue(greaterVersion.greaterOrEqualThan(requiredVersion)); }
