I want to count the number of lines that are inputed in my program but I don't know how. Can someone please help me.

Here's my code:

import java.lang.*;

		List rw = new ArrayList();

		List urw = new ArrayList();
		List uop = new ArrayList();
		List ra = new ArrayList();
		List urand = new ArrayList();
		
		Collections.addAll(rw, reservew);
		Collections.addAll(op, operators);
    	
    	Scanner myObj = new Scanner(System.in);
    	
		System.out.println("Enter your program: ");
		input=myObj.next();
			
		do
		{
			StringTokenizer resword = new StringTokenizer(input, " \\/1234567890!@~$%^&*()_+:;|>.?<,[]{}-=`");

				if(rw.contains(dummy1[a]))
					ReserveWords++;
					
				a++;				
			}

			{
				dummy2[b]=uresword.nextToken();
				
				if(rw.contains(dummy2[b]))
				{					
					if(!urw.contains(dummy2[b]))
					{
						UReserveWords++;
						urw.add(dummy2[b]);
					}

				break;
			
		}while(myObj.hasNext());
		
		System.out.println("\n\nReserved Words: " + ReserveWords);
		System.out.println("Unique Reserved Words: " + UReserveWords);
		System.out.println("Operators: " + Operators);

		System.out.println("Number of Lines: " + lines);
	}
}

With an int variable and the ++ operator after every call to next()?

With an int variable and the ++ operator after every call to next()?

I've done that already, but every time my input is System.out.println(" Number of reserve words: " + Reservewords)...the number of lines is 6...I don't know why...If my input is the do...while loop, the number of lines are correct.
