12: WAP TO ADDN STRINGS IN A VECTOR ARRAY.

12: WAP TO ADDN STRINGS IN A VECTOR ARRAY.

WAP TO ADD N STRINGS IN A VECTOR ARRAY. INPUT NEW STRING S AND CHECK WHETHER IT PRESENT IN THE VECTOR. IF PRESENT DELETE IT OR ADD ANOTHER VECTOR.

Also, you can use the Java compiler to compile a program.

Source code.

import java.util.*;
class vector
{
	public static void main(String args[])
	{
		Vector c= new Vector();
		Scanner s=new Scanner(System.in); // CREATE OBJECT
		
		int n;
		String name;
		int choice;
		do{
	      System.out.println("1.insert\n2.delete\n3.display\nEnter 
              ur choice");
	      choice=s.nextInt();
			switch(choice)
			{
				case 1:  for(int i=1;i<=3;i++)
					{
						 
                                     System.out.println("Enter city");
						name=s.next();								     		
                                         if(c.contains(name))
					{
					   System.out.println("City is 
                                                 already exist");
					}
					else
					{
					 c.addElement(name);
					}
					}
					break;
				case 2: System.out.println("Enter 
                                        city");
					name=s.next();
					if(c.contains(name))
					{
					  c.remove(name);
					}
					else
					{
					    System.out.println("city 
                                         doesnot exist");
					}
					break;
				case 3: 
					Enumeration nam =c.elements();
					System.out.println("cities");
					while(nam.hasMoreElements())
			    System.out.println(nam.nextElement()+" ");
					 System.out.println(" \n");
					break;
			}// END OF SWITCH
			System.out.println("1.yes\n2.no\n");	
			n=s.nextInt();
		}while(n==1);
	}// END OF MAIN
} // END OF CLASS
