Modifier and Type	Method	Description
`abstract void`	`put(String name, boolean val)`	Put the value of the named boolean field into the persistent field.
`abstract void`	`put(String name, byte val)`	Put the value of the named byte field into the persistent field.
`abstract void`	`put(String name, char val)`	Put the value of the named char field into the persistent field.
`abstract void`	`put(String name, double val)`	Put the value of the named double field into the persistent field.
`abstract void`	`put(String name, float val)`	Put the value of the named float field into the persistent field.
`abstract void`	`put(String name, int val)`	Put the value of the named int field into the persistent field.
`abstract void`	`put(String name, long val)`	Put the value of the named long field into the persistent field.
`abstract void`	`put(String name, Object val)`	Put the value of the named Object field into the persistent field.
`abstract void`	`put(String name, short val)`	Put the value of the named short field into the persistent field.
`abstract void`	`write(ObjectOutput out)`	Deprecated. This method does not write the values contained by this `PutField` object in a proper format, and may result in corruption of the serialization stream. The correct way to write `PutField` data is by calling the `ObjectOutputStream.writeFields()` method.

@Deprecated
public abstract void write(ObjectOutput out)
                                throws IOException
```
    Deprecated. This method does not write the values contained by this PutField object in a proper format, and may result in corruption of the serialization stream. The correct way to write PutField data is by calling the ObjectOutputStream.writeFields() method.
    
    Write the data and fields to the specified ObjectOutput stream, which must be the same stream that produced this PutField object.
    
    Parameters:
    
    out - the stream to write the data and fields to
    
    Throws:
    
    IOException - if I/O errors occur while writing to the underlying stream
    
    IllegalArgumentException - if the specified stream is not the same stream that produced this PutField object
