Importing Packages

• Can always use class without importing
  

  java.util.Scanner in = new java.util.Scanner(System.in);

• Tedious to use fully qualified name
• Import lets you use shorter class name
  

  import java.util.Scanner;
  . . .
  Scanner in = new Scanner(System.in)

• Can import all classes in a package
  

  import java.util.*;
  

• Never need to import java.lang
• You don't need to import other classes in the same package
