CompoundName addAll() method in Java with Examples

The addAll() method of a javax.naming.CompoundName class is used to add all the components of a different compound name object to this CompoundName object.

There are two different addAll() methods.

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

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 compoundName 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 compound name, or if the addition of the components violates the syntax of this compound name (e.g. exceeding the number of components).

Below programs illustrate the CompoundName.addAll() method:

Program 1:

Java

// Java program to demonstrate
// CompoundName.addAll()

import java.util.Properties;
import javax.naming.CompoundName;
import javax.naming.InvalidNameException;

public class GFG {
    public static void main(String[] args)
        throws InvalidNameException
    {

        // need properties for CompoundName
        Properties props = new Properties();
        props.put("jndi.syntax.separator", "@");
        props.put("jndi.syntax.direction",
                  "left_to_right");

        // create compound name object
        CompoundName CompoundName1
            = new CompoundName(
                "1@2@3@4@5@6@7",
                props);

        // different component to add at position 0
        CompoundName differentComponent
            = new CompoundName(
                "9@99@999@9999",
                props);

        // apply addAll() to add All
        // new components at posn 0
        CompoundName newCompoundName
            = (CompoundName)
                  CompoundName1.addAll(
                      0, diffrenetComponent);

        // print value
        System.out.println(
            "Updated CompoundName Object: "
            + newCompoundName);
    }
}

Output:

Updated CompoundName Object: 9@99@999@9999@1@2@3@4@5@6@7

2. addAll(String): This method is used to add all the components of different compound name object passed as input to the end of this compound 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 compoundName, not a new one. The returned value Cannot be null.

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

Below programs illustrate the CompoundName.addAll() method:

Program 1:

Java

// Java program to demonstrate
// CompoundName.addAll()

import java.util.Properties;
import javax.naming.CompoundName;
import javax.naming.InvalidNameException;

public class GFG {
    public static void main(String[] args)
        throws InvalidNameException
    {

        // need properties for CompoundName
        Properties props = new Properties();
        props.put("jndi.syntax.separator", "@");
        props.put("jndi.syntax.direction",
                  "left_to_right");

        // create compound name object
        CompoundName CompoundName1
            = new CompoundName(
                "1@2@3@4@5@6@7", props);

        // different component to add at position 0
        CompoundName differentComponent
            = new CompoundName(
                "9@99@999@9999", props);

        // apply addAll() to add All
        // new components at posn 0
        CompoundName newCompoundName
            = (CompoundName)
                  CompoundName1.addAll(
                      diffrenetComponent);

        // print value
        System.out.println(
            "Updated CompoundName Object: "
            + newCompoundName);
    }
}

Output:

Updated CompoundName Object: 1@2@3@4@5@6@7@9@99@999@9999
