I want to convert this method to search by first letter instead of the full name (for example if the user enter F it shows all node that have F letter in its name )

 

public void search() {

 

int flag = 0;

 

Node pointer;

 

System.out.print("Enter the name you want to search: ");

 

String key = input.next();

 

pointer = root;

 

   while (pointer != null)

 

   {

 

if (pointer.name.compareTo(key) == 0) {

 

flag = 1;

 

System.out.println("RECORD FOUND");

 

System.out.println();

 

System.out.println("--------------------------");

 

System.out.println("NAME\t| CONTACT NUMBER ");

 

System.out.println("--------------------------");

 

System.out.println("" + pointer.name + "\t " + pointer.number);

 

System.out.println("------------------------");

 

break;

 

}

 

if ((pointer.name).compareTo(key) > 0) {

 

pointer = pointer.left;

 

} else {

 

pointer = pointer.right;

 

}

 

}

 

if (flag == 0) {

 

System.out.println("RECORD NOT FOUND");

 

}

 

}
