New to java programming, need help on short piece of code.

import java.util.*;
// I have created a simple Interviewer where it asks for name and age and ask if it is correct with a yes/no function.
// I have compiled and ran this in Eclipse IDE, i have not encountered any critical errors but i have with yellow warnings.
// I'm struggling with using the Scanner utility.
// Apologises with structure, new to this.
public class scanner {
	
	public static void main(String[] args) {
		Scanner userInput = new Scanner(System.in); // Yellow warning, is this right? Says 'convert local variable to field'*
		
		String version = "v1";
		String wlcmsg;

		
		wlcmsg = "Welcome to Interviwer " + version + ".";
		System.out.print(wlcmsg); // Welcome message.
		System.out.println(" Please press 'enter' to continue...");
		
		try {
			System.in.read();
		}
		catch (Exception e) { //Works fine, Press the 'enter' key and takes me to next step.
			
		}
			for(int clear = 0; clear <= 50; clear++)
			  {
			     System.out.println(" ");  // Prints 50 Lines of spaces, Using this as clearing screen but not sure if this is recommended. Any easier way or other code to do the same concept? **
		        }
			
			System.out.println("\n");
			String blank = userInput.nextLine(); // I AM NOT SURE I NEED THIS? When i remove line 27 & 28, userInput does not work for line 29/30.
			System.out.println(blank + "Please enter your name: ");
			String name = userInput.nextLine();
		
		for(int clear = 0; clear <= 50; clear++)
		  {
		     System.out.println(" ") ;  //**
	        }
		
			System.out.print("Hello " + name + ", I am your personal interviewer " + version + "\n" + "So, How old are you?");
			int age = userInput.nextInt();
		
		for(int clear = 0; clear <= 50; clear++)
			
		  {
		     System.out.println(" ") ; //**
		  }	

			System.out.println("So your name is " + name + " and you are " + age + " years old." + "\n" + "Is this correct?");
			Scanner options = new Scanner(System.in); //*
			
		if(options.next().equalsIgnoreCase("y")||options.next().equalsIgnoreCase("options")) { // The yes option seems to work but no and the invalid characters does not seem to print out. Have i went wrong here?
		    System.out.println("This will be fun");
		} else if(options.next().equalsIgnoreCase("n")||options.next().equalsIgnoreCase("no")) {
		    System.out.println("Maybe next time");
		} else { 
		System.out.println("Invalid character");

	}
