订阅現在讓我們來看看JDK5中有什麽更激動人心的改進和創新，我要介紹的是其中的一個比較實用的特性：靜態導入！
直接看一段代碼吧，很容易就可以了解：
package staticEx;
public class TranscendentalConstants {
public static final double PI = 3.14159;
public static final double E = 2.71828;
}
public class IrrationalConstants {
public static final double SQRT_TWO = 1.414;
public static final double SQRT_THREE = 1.732;
}
//在類中導入靜態變量和方法
package staticEx;
import static staticEx.IrrationalConstants.SQRT_TWO;
import static staticEx.IrrationalConstants.SQRT_THREE;
import static staticEx.TranscendentalConstants.PI;
public class ConstantsWithStaticImport {
public static double sinPiOverFour() {
return SQRT_TWO / 2;
}
public static void main(String[] args) {
System.out.println("Pi is approximately " + PI);
System.out.println("The sin of Pi/4 is about " +
sinPiOverFour());
}
}
JDK5提供了導入靜態類，方法，和屬性的新特性，上手也很容易，至于適用的地方嘛，各位就自己看著辦羅！
