### Question:
PlatformDescription { public static boolean isThisJVM(String name) { return JVM_NAME.startsWith(name); } private  PlatformDescription(); static String describePlatform(); static boolean isThisJVM(String name); static boolean isAndroidOpenJDK(); static boolean isAfterJigsaw(); static boolean isAfterJava11(); static boolean isGoogleAppEngine(); static final String GNU; static final String HOTSPOT; @Deprecated
   static final String SUN; static final String OPENJDK; static final String PERC; static final String DALVIK; static final String SPECIFICATION_VERSION; static final String VM_VERSION; static final String VM_INFO; static final String VENDOR_VERSION; static final String VENDOR; static final String JVM_NAME; static final int ANDROID_VERSION; static final boolean IS_ANDROID_OPENJDK; static final String GAE_VERSION; }### Answer:
@Test public void isJvmName() { PlatformDescription.isThisJVM(PlatformDescription.HOTSPOT); }
@Test public void test() { if(!PlatformDescription.isThisJVM(PlatformDescription.DALVIK)) { assertEquals(0, PlatformDescription.ANDROID_VERSION); } }
