CompositeName addAll() method in Java with Examples
  • Last Updated : 27 Mar, 2020

The addAll() method of a javax.naming.CompositeName class is used to add all the component of a diffrent composite name object to this CompositeName object.
There are two different addAll() methods.

  1. addAll(int, Name): This method is used to add all the component of a different composite name object which is passed as a parameter at a specified position posn in this composite name object. The other components of this composite name object present at or after the position of the first new component are shifted up to accommodate all the components of the different component.

    Syntax:

    public Name addAll(int posn, Name n)
           throws InvalidNameException
    

    Parameters: This method accepts

    • posn which is the index at which to add all the new components and
    • n which is the non-null components to add.

    Return value: This method returns updated CompositeName object, not a new one. The returned value Cannot be null.

    Exception: This method throws ArrayIndexOutOfBoundsException If posn is outside the specified range and InvalidNameException If n is not a composite name, or if the addition of the components violates the syntax of this composite name (e.g. exceeding number of components).



    Below programs illustrate the CompositeName.addAll() method:
    Program 1:




    // Java program to demonstrate
    // CompositeName.addAll()
      
    import java.util.Properties;
    import javax.naming.CompositeName;
    import javax.naming.InvalidNameException;
      
    public class GFG {
        public static void main(String[] args)
            throws InvalidNameException
        {
      
            // create composite name object
            CompositeName CompositeName1
                = new CompositeName(
                    "1/2/3/4/5/6/7/8/9");
      
            // different component to add at position 0
            CompositeName diffrenetComponent
                = new CompositeName("9/99/999/9999");
      
            // apply addAll() to add All new components at posn 0
            CompositeName newCompositeName
                = (CompositeName)
                      CompositeName1
                          .addAll(
                              0, diffrenetComponent);
      
            // print value
            System.out.println(
                "Updated CompositeName Object: "
                + newCompositeName);
        }
    }

    
    

    Output:

    Updated CompositeName Object: 9/99/999/9999/1/2/3/4/5/6/7/8/9
    
  2. addAll(Name): Thie method is used to add all the components of diffrent composite name object passeed as input to the end of this composite name.
    Syntax:

    public Name addAll(Name suffix)
                throws InvalidNameException
    

    Parameters: This method accepts suffix which is the non-null components to add.

    Return value: This method returns updated CompositeName, not a new one. The returned value Cannot be null.

    Exception: This method throws InvalidNameException if the suffix is not a composite name, or if the addition of the components violates the syntax of this composite name (e.g. exceeding number of components).

    Below programs illustrate the CompositeName.addAll() method:
    Program 1:




    // Java program to demonstrate
    // CompositeName.addAll()
      
    import java.util.Properties;
    import javax.naming.CompositeName;
    import javax.naming.InvalidNameException;
      
    public class GFG {
        public static void main(String[] args)
            throws InvalidNameException
        {
      
            // create composite name object
            CompositeName CompositeName1
                = new CompositeName("1/2/3/4/5/6/7");
      
            // different component to add at position 0
            CompositeName diffrenetComponent
                = new CompositeName("9/99/999/9999");
      
            // apply addAll() to add All
            // new components at posn 0
            CompositeName newCompositeName
                = (CompositeName)
                      CompositeName1
                          .addAll(diffrenetComponent);
      
            // print value
            System.out.println(
                "Updated CompositeName Object: "
                + newCompositeName);
        }
    }

    
    

    Output:

    Updated CompositeName Object: 1/2/3/4/5/6/7/9/99/999/9999
