Methods

Method	Description
com.google.gson.Gson.excluder()	This method by accident exposes an internal Gson class; it might be removed in a future version.
com.google.gson.GsonBuilder.setDateFormat(int)	Counterintuitively, despite this method taking only a 'date style' Gson will use a format which includes both date and time, with the 'time style' being the last value set by GsonBuilder.setDateFormat(int, int). Therefore prefer using GsonBuilder.setDateFormat(int, int) and explicitly provide the desired 'time style'.
com.google.gson.GsonBuilder.setLenient()	This method is equivalent to calling GsonBuilder.setStrictness(Strictness) with Strictness.LENIENT: setStrictness(Strictness.LENIENT)
com.google.gson.JsonArray.getAsCharacter()	This method is misleading, as it does not get this element as a char but rather as a string's first character.
com.google.gson.JsonElement.getAsCharacter()	This method is misleading, as it does not get this element as a char but rather as a string's first character.
com.google.gson.JsonParser.parse(String)	Use JsonParser.parseString(java.lang.String)
com.google.gson.JsonPrimitive.getAsCharacter()	This method is misleading, as it does not get this element as a char but rather as a string's first character.
com.google.gson.reflect.TypeToken.isAssignableFrom(Class<?>)	this implementation may be inconsistent with javac for types with wildcards.
com.google.gson.stream.JsonReader.setLenient(boolean)	Please use JsonReader.setStrictness(Strictness) instead. JsonReader.setLenient(true) should be replaced by JsonReader.setStrictness(Strictness.LENIENT) and JsonReader.setLenient(false) should be replaced by JsonReader.setStrictness(Strictness.LEGACY_STRICT). However, if you used setLenient(false) before, you might prefer Strictness.STRICT now instead.
com.google.gson.stream.JsonWriter.setLenient(boolean)	Please use JsonWriter.setStrictness(Strictness) instead. JsonWriter.setLenient(true) should be replaced by JsonWriter.setStrictness(Strictness.LENIENT) and JsonWriter.setLenient(false) should be replaced by JsonWriter.setStrictness(Strictness.LEGACY_STRICT). However, if you used setLenient(false) before, you might prefer Strictness.STRICT now instead.

Constructors

Constructor	Description
com.google.gson.JsonElement()	Creating custom JsonElement subclasses is highly discouraged and can lead to undefined behavior. This constructor is only kept for backward compatibility.
com.google.gson.JsonNull()	Deprecated since Gson version 1.8, use JsonNull.INSTANCE instead.
com.google.gson.JsonParser()	No need to instantiate this class, use the static methods instead.
