```
public final class JSONObject
extends JSONCollection
implements Map<String,Object>
```
A modifiable set of name/value mappings. Names are unique, non-null strings. Values may be any mix of JSONObjects, JSONArrays, Strings, Booleans, Integers, Longs, Doubles or NULL. Values may not be null, NaNs, infinities, or of any type not listed here.
This class can coerce values to another type when requested.
- When the requested type is a boolean, strings will be coerced using a case-insensitive comparison to "true" and "false".
- When the requested type is a double, other Number types will be coerced using doubleValue. Strings that can be coerced using Double.valueOf(String) will be.
- When the requested type is an int, other Number types will be coerced using intValue. Strings that can be coerced using Double.valueOf(String) will be, and then cast to int.
- When the requested type is a long, other Number types will be coerced using longValue. Strings that can be coerced using Double.valueOf(String) will be, and then cast to long. This two-step conversion is lossy for very large values. For example, the string "9223372036854775806" yields the long 9223372036854775807.
- When the requested type is a String, other non-null values will be coerced using String.valueOf(Object). Although null cannot be coerced, the sentinel value NULL is coerced to the string "null".
This class can look up both mandatory and optional values:
- Use getType() to retrieve a mandatory value. This fails with a RuntimeException if the requested name has no value or if the value cannot be coerced to the requested type.
- Use opt() to retrieve an optional value.
Warning: this class represents null in two incompatible ways: the standard Java null reference, and the sentinel value NULL. In particular, calling put(name, null) removes the named entry from the object but put(name, JSONObject.NULL) stores an entry whose value is JSONObject.NULL.
Instances of this class are not thread safe.

- Field Detail
  - NULL
```
public static final Object NULL
```
    A sentinel value used to explicitly define a name with no value. Unlike null, names with this value:
    - show up in the names() array
    - show up in the keys() iterator
    - return true for has(String)
    - do not throw on get(java.lang.Object)
    - are included in the encoded JSON string.
    This value violates the general contract of Object.equals(java.lang.Object) by returning true when compared to null. Its JSONCollection.toString() method returns "null".
- Constructor Detail
  - JSONObject
```
public JSONObject()
```
    Creates a JSONObject with no name/value mappings.
  - JSONObject
```
public JSONObject(String json)
```
    Creates a new JSONObject with name/value mappings from the JSON string.
    
    Parameters:
    
    json - a JSON-encoded string containing an object.
    
    Throws:
    
    RuntimeException - if the parse fails or doesn't yield a JSONObject.
  - JSONObject
```
public JSONObject(JSONObject copyFrom,
                  String... names)
```
    Creates a new JSONObject by copying mappings for the listed names from the given object. Names that aren't present in copyFrom will be skipped.
    
    Parameters:
    
    copyFrom - The source object.
    
    names - The names of the fields to copy.
    
    Throws:
    
    RuntimeException - On internal errors. Shouldn't happen.
  - JSONObject
```
public JSONObject(Object... keysAndValues)
```
    Constructs a new JSONObject using a series of String keys and object values. Object values should be compatible with put(String, Object). Keys must be strings (toString() will be invoked on each key). Prior to release 5.4, keysAndValues was type String...; changing it to Object... makes it much easier to initialize a JSONObject in a single statement, which is more readable.
    
    Since:
    
    5.2.0
- Method Detail
  - copy
```
public JSONObject copy()
```
    Returns a new JSONObject that is a shallow copy of this JSONObject.
    
    Since:
    
    5.4
  - length
```
@Deprecated
public int length()
```
    Deprecated. Use size() instead.
    
    Returns the number of name/value mappings in this object.
    
    Returns:
    
    the length of this.
  - put
```
public JSONObject put(String name,
                      Object value)
```
    Maps name to value, clobbering any existing name/value mapping with the same name. If the value is null, any existing mapping for name is removed.
    
    Specified by:
    
    put in interface Map<String,Object>
    
    Parameters:
    
    name - The name of the new value.
    
    value - a JSONObject, JSONArray, String, Boolean, Integer, Long, Double, NULL, or null. May not be NaNs or infinities.
    
    Returns:
    
    this object.
    
    Throws:
    
    IllegalArgumentException - if the value is an invalid double (infinite or NaN).
  - accumulate
```
public JSONObject accumulate(String name,
                             Object value)
```
    Appends value to the array already mapped to name. If this object has no mapping for name, this inserts a new mapping. If the mapping exists but its value is not an array, the existing and new values are inserted in order into a new array which is itself mapped to name. In aggregate, this allows values to be added to a mapping one at a time. Note that append(String, Object) provides better semantics. In particular, the mapping for name will always be a JSONArray. Using accumulate will result in either a JSONArray or a mapping whose type is the type of value depending on the number of calls to it.
    
    Parameters:
    
    name - The name of the field to change.
    
    value - a JSONObject, JSONArray, String, Boolean, Integer, Long, Double, NULL or null. May not be NaNs or infinities.
    
    Returns:
    
    this object after mutation.
    
    Throws:
    
    RuntimeException - If the object being added is an invalid number.
  - append
```
public JSONObject append(String name,
                         Object value)
```
    Appends values to the array mapped to name. A new JSONArray mapping for name will be inserted if no mapping exists. If the existing mapping for name is not a JSONArray, a RuntimeException will be thrown.
    
    Parameters:
    
    name - The name of the array to which the value should be appended.
    
    value - The value to append.
    
    Returns:
    
    this object.
    
    Throws:
    
    JSONTypeMismatchException - if name is null or if the mapping for name is non-null and is not a JSONArray.
  - isNull
```
public boolean isNull(String name)
```
    Returns true if this object has no mapping for name or if it has a mapping whose value is NULL.
    
    Parameters:

    Returns:
    
    true if the field doesn't exist or is null.

  - keySet
```
public Set<String> keySet()
```
    Returns a Set view of the keys contained in this JSONObject. The set is backed by the JSONObject, so changes to the map are reflected in the set, and vice-versa.
