It's because in ide's like eclipse it doesn't like the console object. Change it to Scanner object for reading input and 

System.out.print();

for doing print to console.

Can also do

System.out.printf();

which is equivalent to 

console.printf();

To make a Scanner object its like this:

import java.util.Scanner;

Scanner s = new Scanner(System.in);

To use it for user input is like this:

String name = s.nextLine();

System.out.printf("Hello %s",name);

Thank you. i thought import java.io.Console; the importing of package was already sufficient.
