CompositeName startsWith() method in Java with Examples
Last Updated :
27 Mar, 2020
The startsWith() method of a javax.naming.CompositeName class is used to check whether composite name which is passed as a parameter is a prefix of this composite name or not. A composite name ‘X’ is a prefix of this composite name if this composite name object ends with ‘X’. If X is null or not a composite name object, false is returned.
Syntax:
public boolean startsWith(Name n)
Parameters: This method accepts Name object n which is the possibly null composite name to check.
Return value: This method returns true if n is a CompositeName and is a prefix of this composite name, false otherwise.
Below programs illustrate the CompositeName.startsWith() method:
Program 1:
import java.util.Properties;
import javax.naming.CompositeName;
import javax.naming.InvalidNameException;
public class GFG {
public static void main(String[] args)
throws InvalidNameException
{
CompositeName CompositeName1
= new CompositeName( "1:2:4:6" );
CompositeName CompositeName2
= new CompositeName( "2:4:6" );
boolean Flag
= CompositeName1
.startsWith(CompositeName2);
if (Flag)
System.out.println(
"CompositeName1 starts with "
+ " CompositeName2" );
else
System.out.println(
"CompositeName1 not starts with "
+ " CompositeName2" );
}
}
|
Output:
CompositeName1 not starts with CompositeName2
Program 2:
import java.util.Properties;
import javax.naming.CompositeName;
import javax.naming.InvalidNameException;
public class GFG {
public static void main(String[] args)
throws InvalidNameException
{
CompositeName CompositeName1
= new CompositeName(
"ca/eaaa/daaa/vaaa/a/b/z/y/x/f" );
CompositeName CompositeName2
= new CompositeName(
"ca/eaaa/daaa" );
boolean Flag
= CompositeName1
.startsWith(CompositeName2);
if (Flag)
System.out.println(
"CompositeName1 starts with "
+ " CompositeName2" );
else
System.out.println(
"CompositeName1 not starts with "
+ " CompositeName2" );
}
}
|
Output:
CompositeName1 starts with CompositeName2
