Static import is a feature introduced in the Java programming language that allows members (fields and methods) which have been scoped within their container class as public static, to be used in Java code without specifying the class in which the field has been defined. This feature was introduced into the language in version 5.0.
The feature provides a typesafe mechanism to include constants into code without having to reference the class that originally defined the field. It also helps to deprecate the practice of creating a constant interface (an interface that only defines constants then writing a class implementing that interface, which is considered an inappropriate use of interfaces.[1])
The mechanism can be used to reference individual members of a class:
publicclassHelloWorld{publicstaticvoidmain(String[]args){System.out.println("Hello World!");System.out.println("Considering a circle with a diameter of 5 cm, it has");System.out.println("a circumference of "+(Math.PI*5)+" cm");System.out.println("and an area of "+(Math.PI*Math.pow(2.5,2))+" sq. cm");}}
Can instead be written as:
import staticjava.lang.Math.*;import staticjava.lang.System.out;publicclassHelloWorld{publicstaticvoidmain(String[]args){out.println("Hello World!");out.println("Considering a circle with a diameter of 5 cm, it has");out.println("a circumference of "+(PI*5)+" cm");out.println("and an area of "+(PI*pow(2.5,2))+" sq. cm");}}
