Steps to create Packages in Java

 

Here are the steps to create a package in Java:

---

1. Define the Package

• Use the package keyword at the very top of the Java file.
• Example:

  package mypackage;
  

---

2. Organize Your Files

• Create a sub directory in the current directory with a name that matches the package name.
• For example, if your package is mypackage, create a folder named mypackage.

---

3. Write Your Java Class

• Save your Java file inside the corresponding folder.
• Example:

  package mypackage;
  
  public class MyClass {
      public void displayMessage() {
          System.out.println("Hello from MyClass in mypackage!");
      }
  }
  

---

4. Compile the Package

• After saving the file, move to the parent directory by entering cd.. at the command prompt.
• Navigate to the parent directory of the package folder in the terminal/command prompt.
• Use the javac command to compile the file:

  javac mypackage/MyClass.java
  

---

5. Use the Package

• To use the package in another Java file, import it using the import statement.
• Example:

  import mypackage.MyClass;
  
  public class Main {
      public static void main(String[] args) {
          MyClass obj = new MyClass();
          obj.displayMessage();
      }
  }
