7,786 PointsIt'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);
