Deprecated ClassesClassDescriptionThis class has moved to
com.google.common.util.concurrent. Please useForwardingBlockingDequeinstead.UseTraverserinstead. All instance methods have their equivalent on the result ofTraverser.forTree(tree)wheretreeimplementsSuccessorsFunction, which has a similar API asTreeTraverser.children(T)or can be the same lambda function as passed intoTreeTraverser.using(Function).This class is scheduled to be removed in October 2019.

Deprecated Exception ClassesException ClassDescriptionThis exception is no longer thrown by
com.google.common. Previously, it was thrown byMapMakercomputing maps. When support for computing maps was removed fromMapMaker, it was added toCacheBuilder, which throwsExecutionException,UncheckedExecutionException, andExecutionError. Any code that is still catchingComputationExceptionmay need to be updated to catch some of those types instead. (Note that this type, though deprecated, is not planned to be removed from Guava.)

Deprecated MethodsMethodDescriptionProvided only to satisfy the

UseThrowable.getStackTrace()directly, or where possible use thejava.lang.StackWalker.walkmethod introduced in JDK 9.This method always returns false on JDK versions past JDK 8 and on all Android versions.To preserve behavior, usethrow eorthrow new RuntimeException(e)directly, or use a combination ofThrowables.throwIfUnchecked(java.lang.Throwable)andthrow new RuntimeException(e). But consider whether users would be better off if your API threw a different type of exception. For background on the deprecation, read Why we deprecatedThrowables.propagate.UseThrowables.throwIfInstanceOf(java.lang.Throwable, java.lang.Class<X>), which has the same behavior but rejectsnull.UseThrowables.throwIfUnchecked(java.lang.Throwable), which has the same behavior but rejectsnull.Use a combination ofThrowables.throwIfInstanceOf(java.lang.Throwable, java.lang.Class<X>)andThrowables.throwIfUnchecked(java.lang.Throwable), which togther provide the same behavior except that they rejectnull.Use a combination of two calls toThrowables.throwIfInstanceOf(java.lang.Throwable, java.lang.Class<X>)and one call toThrowables.throwIfUnchecked(java.lang.Throwable), which togther provide the same behavior except that they rejectnull.Provided to satisfy theFunctioninterface; useLoadingCache.get(K)orLoadingCache.getUnchecked(K)instead.For aListMultimapthat automatically trims to size, useImmutableListMultimap. If you need a mutable collection, remove thetrimToSizecall, or switch to aHashMap<K, ArrayList<V>>.UseComparisonChain.compareFalseFirst(boolean, boolean); or, if the parameters passed are being either negated or reversed, undo the negation or reversal and useComparisonChain.compareTrueFirst(boolean, boolean).Internal method, useMultiset.entrySet().instances ofFluentIterabledon't need to be converted toFluentIterableThis method does not make sense for bimaps and should not be called.Unsupported operation.Unsupported operation.Unsupported operation.Unsupported operation.Unsupported operation.Unsupported operation.Unsupported operation.Unsupported operation.Unsupported operation.Unsupported operation.Unsupported operation.There is no reason to use this;

But if you can choose your hash function, avoid MD5, which is neither fast nor secure. As of January 2017, we suggest:- For security:
Hashing.sha256()or a higher-level API. - For speed:
Hashing.goodFastHash(int), though see its docs for caveats.
This implementation produces incorrect hash values from theHashFunction.hashString(java.lang.CharSequence, java.nio.charset.Charset)method if the string contains non-BMP characters.

This method is dangerous as it discards the high byte of every character. For UTF-8, usewrite(s.getBytes(StandardCharsets.UTF_8)).PreferasCharSink(to, charset, FileWriteMode.APPEND).write(from). This method is scheduled to be removed in October 2019.PreferasCharSource(from, charset).copyTo(to).For Android users, see the Data and File Storage overview to select an appropriate temporary directory (perhapscontext.getCacheDir()), and create your own directory under that. (For example, you might usenew File(context.getCacheDir(), "directoryname").mkdir(), or, if you need an arbitrary number of temporary directories, you might have to generate multiple directory names in a loop untilmkdir()returnstrue.) For JRE users, preferFiles.createTempDirectory(java.nio.file.Path, java.lang.String, java.nio.file.attribute.FileAttribute<?>...), transforming it to aFileusingtoFile()if needed. To restrict permissions as this method does, passPosixFilePermissions.asFileAttribute(PosixFilePermissions.fromString("rwx------"))to your call tocreateTempDirectory.PreferasByteSource(file).hash(hashFunction).PreferasByteSource(file).read(processor).PreferasCharSource(file, charset).readFirstLine().PreferasCharSource(file, charset).readLines(callback).PreferasCharSource(file, charset).read().PreferasCharSink(to, charset).write(from).The semantics ofwriteBytes(String s)are considered dangerous. Please useLittleEndianDataOutputStream.writeUTF(String s),LittleEndianDataOutputStream.writeChars(String s)or another write method instead.UseStats.meanOf(java.lang.Iterable<? extends java.lang.Number>)instead, noting the less strict handling of non-finite values.UseStats.meanOf(java.lang.Iterable<? extends java.lang.Number>)instead, noting the less strict handling of non-finite values.UseStats.meanOf(java.lang.Iterable<? extends java.lang.Number>)instead, noting the less strict handling of non-finite values.UseStats.meanOf(java.lang.Iterable<? extends java.lang.Number>)instead, noting the less strict handling of non-finite values.UseStats.meanOf(java.lang.Iterable<? extends java.lang.Number>)instead, noting the less strict handling of non-finite values.unsupported operationunsupported operationunsupported operationunsupported operationunsupported operationunsupported operationCreatingFutures of closeable types is dangerous in general because the underlying value may never be closed if theFutureis canceled after its operation begins. Consider replacing code that createsListenableFutures of closeable types, including those that pass them to this method, withClosingFuture.submit(ClosingCallable, Executor)in order to ensure that resources do not leak. Or, to start a pipeline with aListenableFuturethat doesn't create values that should be closed, useClosingFuture.from(com.google.common.util.concurrent.ListenableFuture<V>).no need to use this - For security:
