  - deepCopy
```
public abstract JsonElement deepCopy()
```
    Returns a deep copy of this element. Immutable elements like primitives and nulls are not copied.
    
    Since:
    
    2.8.2
  - isJsonArray
```
public boolean isJsonArray()
```
    provides check for verifying if this element is an array or not.
    
    Returns:
    
    true if this element is of type JsonArray, false otherwise.
  - isJsonObject
```
public boolean isJsonObject()
```
    provides check for verifying if this element is a Json object or not.
    
    Returns:
    
    true if this element is of type JsonObject, false otherwise.
  - isJsonPrimitive
```
public boolean isJsonPrimitive()
```
    provides check for verifying if this element is a primitive or not.
    
    Returns:
    
    true if this element is of type JsonPrimitive, false otherwise.

```
public boolean isJsonNull()
```
    provides check for verifying if this element represents a null value or not.
    
    Returns:
    
    true if this element is of type JsonNull, false otherwise.

  - getAsJsonObject
```
public JsonObject getAsJsonObject()
```
    convenience method to get this element as a JsonObject. If the element is of some other type, a IllegalStateException will result. Hence it is best to use this method after ensuring that this element is of the desired type by calling isJsonObject() first.
    
    Returns:
    
    get this element as a JsonObject.
