示例1: computeLatestAvailableVersionFromVersionSpec
import java.util.TreeSet; //導入方法依賴的package包/類
public static int computeLatestAvailableVersionFromVersionSpec(TreeSet<Integer> allAvailableFacebookAppVersions, int latestSdkVersion, int[] versionSpec) {
int versionSpecIndex = versionSpec.length - 1;
Iterator<Integer> fbAppVersionsIterator = allAvailableFacebookAppVersions.descendingIterator();
int latestFacebookAppVersion = -1;
while (fbAppVersionsIterator.hasNext()) {
int fbAppVersion = ((Integer) fbAppVersionsIterator.next()).intValue();
