Keep your Java code clean. Use packages and constructors to organize your work.

Packages group related classes. They work like folders. They stop name conflicts. They manage access.

Constructors initialize your objects. They share the class name. They have no return type.

Learn the three types:

• Default Constructor: Java makes this if you write none.
• No-Argument Constructor: You write this without parameters.
• Parameterized Constructor: You write this with parameters.

Know the difference: The compiler provides the default constructor. The programmer writes the no-argument constructor.
