CompoundName startsWith() method in Java with Examples
Last Updated :

The startsWith() method of a javax.naming.CompoundName class is used to check whether compound name which is passed as a parameter is a prefix of this compound name or not. A compound name ‘X’ is a prefix of this compound name if this compound name object ends with ‘X’. If X is null or not a compound name object, false is returned.
Syntax:
public boolean startsWith(Name n)
Parameters: This method accepts n which is the possibly null compound name to check.
Return value: This method returns true if n is a CompoundName and is a prefix of this compound name, false otherwise.
Below programs illustrate the CompoundName.startsWith() method:
Program 1:
import java.util.Properties;
import javax.naming.CompoundName;
import javax.naming.InvalidNameException;
public class GFG {
public static void main(String[] args)
throws InvalidNameException
{
Properties props = new Properties();
props.put( "jndi.syntax.separator" , ":" );
props.put( "jndi.syntax.direction" ,
"left_to_right" );
CompoundName CompoundName1
= new CompoundName(
"1:2:4:6" , props);
CompoundName CompoundName2
= new CompoundName(
"2:4:6" , props);
boolean Flag
= CompoundName1
.startsWith(CompoundName2);
if (Flag)
System.out.println(
"CompoundName1 starts with "
+ " CompoundName2" );
else
System.out.println(
"CompoundName1 not starts with "
+ " CompoundName2" );
}
}
|
Output:
CompoundName1 not starts with CompoundName2
Program 2:
import java.util.Properties;
import javax.naming.CompoundName;
import javax.naming.InvalidNameException;
public class GFG {
public static void main(String[] args)
throws InvalidNameException
{
Properties props = new Properties();
props.put( "jndi.syntax.separator" , "/" );
props.put( "jndi.syntax.direction" ,
"left_to_right" );
CompoundName CompoundName1
= new CompoundName(
"c/e/d/v/a/b/z/y/x/f" ,
props);
CompoundName CompoundName2
= new CompoundName(
"c/e/d" ,
props);
boolean Flag
= CompoundName1
.startsWith(CompoundName2);
if (Flag)
System.out.println(
"CompoundName1 starts with "
+ " CompoundName2" );
else
System.out.println(
"CompoundName1 not starts with "
+ " CompoundName2" );
}
}
|
Output:
CompoundName1 starts with CompoundName2
