Static import in java


Static import:

Static import is a feature which provides the facility to access static members of a class directly without using class name.

Example:

Display.java

package display;
/**
 * This class is used to display entered text.
 * @author CodesJava
 */
public class Display {
        public static void displayText(String text){
               System.out.println(text);
        }
}

Test

package test;
 
import static display.Display.*;
/**
 * This class is used to show static import example.
 * @author CodesJava
 */
public class Test {
       public static void main(String args[]){
              displayText("Hello java.");
       }
}

Output:

Hello java.

Advantages of static import:

It reduces the code by removing the need of class name to access static data members.

Disadvantages of static import:

1. It reduces the code readability because of class name absence.
2. If two classes have static data member with same name and both classes are statically imported. Then java will throw compile time error.

Difference between import and static import.

            import                static import
  1. Access classes and interfaces without package name.
  2. Accessibility is for classes and interfaces.
  3. import not result in a unreadable code.
  4. No code conflict.
