CompositeName startsWith() method in Java with Examples
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:
// Java program to demonstrate // CompositeName.startsWith() 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( "1:2:4:6" ); CompositeName CompositeName2 = new CompositeName( "2:4:6" ); // apply startsWith() boolean Flag = CompositeName1 .startsWith(CompositeName2); // print value if (Flag) System.out.println( "CompositeName1 starts with " + " CompositeName2" ); else System.out.println( "CompositeName1 not starts with " + " CompositeName2" ); } } |
CompositeName1 not starts with CompositeName2
Program 2:
// Java program to demonstrate // CompositeName.startsWith() method 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( "ca/eaaa/daaa/vaaa/a/b/z/y/x/f" ); CompositeName CompositeName2 = new CompositeName( "ca/eaaa/daaa" ); // apply startsWith() boolean Flag = CompositeName1 .startsWith(CompositeName2); // print value if (Flag) System.out.println( "CompositeName1 starts with " + " CompositeName2" ); else System.out.println( "CompositeName1 not starts with " + " CompositeName2" ); } } |
CompositeName1 starts with CompositeName2
