### Question:
Version { public static boolean hasQualifier( String version ) { return !isEmpty( getQualifier( version ) ); } private  Version(); static String getBuildNumber(String version); static int getBuildNumberPadding( int incrementalSerialSuffixPadding, Set<String> versions ); static String getMMM(String version); static String getOsgiVersion(String version); static String getQualifier(String version); static String getQualifierBase(String version); static String getQualifierWithDelim(String version); static String getSnapshot( String version ); static String getSnapshotWithDelim( String version ); static boolean hasBuildNumber( String version ); static boolean hasQualifier( String version ); static boolean isEmpty( String string ); static boolean isSnapshot( String version ); static boolean isValidOSGi(String version); static String removeBuildNumber( String version ); static String removeSnapshot( String version ); static String appendQualifierSuffix( final String version, final String suffix ); static String setBuildNumber( String version, String buildNumber ); static String setSnapshot( String version, boolean snapshot ); static int findHighestMatchingBuildNumber(String version, Set<String> versionSet ); static int getIntegerBuildNumber( String version ); static final String PROJECT_VERSION; }### Answer:
@Test public void testHasQualifier() { assertTrue( Version.hasQualifier( "1.0-SNAPSHOT" ) ); assertFalse( Version.hasQualifier( "1.0.0" ) ); assertTrue( Version.hasQualifier( "1.0.0.Final" ) ); assertTrue( Version.hasQualifier( "1.0.Final-rebuild" ) ); assertTrue( Version.hasQualifier( "1.0.Final-rebuild-1" ) ); assertTrue( Version.hasQualifier( "7.18.1.20190312-prod" ) ); }
