Kid Class

A Kid has a String name, an int age, and a String interests.

To write:

• Constructor: includes all of information above.
• Constructor: you are allowed to omit the interests, in which case teenagers (ages 13-19) have an interest of “listening to music” and everyone else has an interest of “having fun”.
• public String introduce()
• public void growUp(): Increases age by three.

Example usage:

     Kid alice = new Kid("Alice", 13, "skating");
     String s = alice.introduce();
     System.out.println(s);
     // "I'm Alice. I am 13 years old and like skating."
     alice.growUp(); // now 16

     Kid ken = new Kid("Ken", 16);
     String ss = ken.introduce();
     System.out.println(ss);
     // "I'm Ken. I am 16 years old and like listening to music."
