title: How to read and save an Integer, Double, and String to a variable?
body: <p>For a online course I'm taking,I'm trying to save the 2nd set of  integer, double, and string that I defined to  variables, after reading them (the 2nd set) using a scanner. The problem is I don't know how to do that to the 2nd set of  variables that I defined. I've tried instantiating them to a new variable,but I keep running into errors. I need help to read each variable and then save them.   </p>

      int j = 4;
      double y = 9.0;
      String k = "is the best place to learn and practice coding!";
  
  
      int j = new j();
      double y = new y();
      String k = new k();
      j.scanner.nextInt();
      y.scanner.nextDouble();
      k.scanner.nextLine();
  
  
      System.out.print(j + i);
      System.out.print(d + y);
      System.out.print(s + k);
