Debugging issues with one of my methods

Question

public Elevator selectFloor()
    Scanner stdIn = new Scanner(System.in);
    int newFloor;
    newFloor = stdIn.nextInt();
    System.out.print("Enter the floor that you'd like to go to ==> ");
    If((newFloor >= 0 && newFloor <= 100)) //determines if the new floor is valid
       If(newFloor>this.floor)       //determines if the new floor is higher
          do
          newFloor--;
          System.out.print(newFloor + " ");
          } while (newFloor>this.floor)
       } //end if statement
       else
          do
          newFloor++;
          System.out.print(newFloor + " ");
          } while(newFloor<this.floor) //end do loop
       } // end else
    this.floor = newFloor;
    } // end if statement (input validification)
    else
       System.out.println
       ("Invalid floor selection - must be between 1 and 100.");
    } // end else
       return this;

8 errors
Tool completed with exit code 1
I've spent massive amounts of time trying to resolve the issues. I do not understand exactly why the program is giving me issues about requiring a boolean and why I would want a print statement at the end of a while loop, or what's deal is with the if statements. These are the error messages I get when I try to compile the driver I wrote for it.

Answer 1

Java is case sensitive. Keywords (like 'if') are not capitalized.
Do While loops require a semicolon after the while.
Sun provides tutorials on all of this.
