Scanner cannot be resolved to a type

Just installed eclipse having not been programming for a month...

Code:

import java.util.*;
public class twod {
	public static void  main(String[] args) 
	{
		Scanner in = new Scanner(System.in);
		System.out.println("How many rows?");
		int rows = in.nextInt();
		System.out.println("How many columns?");
		int columns = in.nextInt();
		double[][] table = new double[rows][columns];
		
		double input;
	
		for(int r = 0; r < rows; r++)
		{
			for(int c = 0; c < columns; c++)
			{
				System.out.println(r + "," + c + " :");
				input = in.nextDouble();
				table[r][c] = input;
			}
		}
	
		for(double[] e : table)
		{
			System.out.print(e);
		}
		}//end main
}//end

error:

Code:

Exception in thread "main" java.lang.Error: Unresolved compilation problems:

Code:

~$ java -version

I hope I did the 2D arrays right.
