Клево, теперь можно писать код

public class MyClass {
  
   private int myInt = -1;

   public int getMyInt() {
     return this.myInt;
   }

   public void setMyInt(int myInt) {
     this.myInt = myInt;
   }
}

class Person
  attr_reader :name, :age
  def initialize(name, age)
    @name, @age = name, age
  end
  def <=>(person) # Comparison operator for sorting
    @age <=> person.age
  end
  def to_s
    "#@name (#@age)"
  end
end

SELECT * 
FROM Book
WHERE price > 100.00
ORDER BY title;
