// Get the specification title of myPackage
// using getSpecificationTitle() method
System.out.println(
"Specification title of myPackage: "
+ myPackage.getSpecificationTitle());
}
}
Output:
Package represented by myPackage: package java.lang, Java Platform API Specification, version 1.8
Specification title of myPackage: Java Platform API Specification
例 2:
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to demonstrate
// getSpecificationTitle() method
public class Test {
public static void main(String[] args)
{
// returns the Package object
// for this package
Package myPackage
= Package.getPackage("java.io");
System.out.println(
"Package represented by myPackage: "
+ myPackage.toString());
// Get the name of myPackage
// using getSpecificationTitle() method
System.out.println(
"Specification title of myPackage: "
+ myPackage.getSpecificationTitle());
}
}
Output:
Package represented by myPackage: package java.io, Java Platform API Specification, version 1.8
