Field setShort() method in Java with Examples

The setShort() method of java.lang.reflect.Field is used to set the value of a field as a short on the specified object. When you need to set the value of a field of an object as short then you can use this method to set value over an Object.

Syntax:

public void setShort(Object obj, short s)
         throws IllegalArgumentException,
                IllegalAccessException

Parameters: This method accepts accepts two parameters:



  • obj: which is the object whose field should be modified and
  • s: which is the new value for the field of obj being modified.

Return: This method returns nothing.

Exception: This method throws the following Exception:

  • IllegalAccessException: if this Field object is enforcing Java language access control and the underlying field is either inaccessible or final.
  • IllegalArgumentException: if the specified object is not an instance of the class or interface declaring the underlying field (or a subclass or implementor thereof), or if an unwrapping conversion fails.
  • NullPoshorterException: if the specified object is null and the field is an instance field.
  • ExceptionInInitializerError: if the initialization provoked by this method fails.

        // print value of uniqueNo
        System.out.println(
            "Value of uniqueNo before "
            + "applying setShort is "
            + emp.uniqueNo);
  
        // Get the field object
        Field field
            = Employee.class
                  .getField("uniqueNo");
  
        // Apply setShort Method
        field.setShort(emp, (short)134);
  
        // print value of uniqueNo
        System.out.println(
            "Value of uniqueNo after "
            + "applying setShort is "
            + emp.uniqueNo);
    }
}
  
// sample class
class Employee {
  
    // static short values
    public static short uniqueNo = 239;
}
