用示例将 getImplementationVendor()方法用 Java 打包
原文:https://www . geesforgeks . org/package-getimplementationvender-method-in-Java-with-examples/
java.lang.Package 类 的getImplementationVendor()方法用于获取该包的实现的厂商。方法以字符串形式返回包的实现供应商。
语法:
public String getImplementationVendor()
参数:此方法不接受任何参数。 返回值:该方法将包的实现供应商作为字符串返回，如果知道的话。否则返回空值
下面的程序演示了 getImplementationVendor()方法。
例 1:
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to demonstrate
// getImplementationVendor() method
public class Test {
public static void main(String[] args)
{
// returns the Package object
// for this package
Package myPackage
= Package.getPackage("java.lang");
System.out.println(
"Package represented by myPackage: "
+ myPackage.toString());
// Get the implementation vendor of myPackage
// using getImplementationVendor() method
System.out.println(
"Implementation vendor of myPackage: "
+ myPackage.getImplementationVendor());
}
}
Output:
Package represented by myPackage: package java.lang, Java Platform API Specification, version 1.8
Implementation vendor of myPackage: N/A
例 2:
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to demonstrate
// getImplementationVendor() 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 getImplementationVendor() method
System.out.println(
"Implementation vendor of myPackage: "
+ myPackage.getImplementationVendor());
}
}
Output:
Package represented by myPackage: package java.io, Java Platform API Specification, version 1.8
Implementation vendor of myPackage: N/A
