java.lang.Package类的isCompatibleWith()方法用于检查此程序包的规范版本是否与指定版本兼容。该方法以布尔值返回结果。
用法:
public boolean isCompatibleWith(String desiredVersion)
参数:此方法接受参数parameterVersedVersion,这是要检查兼容性的版本。
返回值:此方法将结果作为布尔值返回。
下面的程序演示了isCompatibleWith()方法。
范例1:
// Java program to demonstrate
// isCompatibleWith() 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());
String desiredVersion = "1.5";
// check if this package is compatible with or not
// using isCompatibleWith() method
System.out.println(
"Is this package compatible with or not:"
+ myPackage.isCompatibleWith(desiredVersion));
}
}
输出:
Package represented by myPackage:package java.lang, Java Platform API Specification, version 1.8 Is this package compatible with or not:true
范例2:
// Java program to demonstrate
// isCompatibleWith() 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());
String desiredVersion = "1.0";
// check if this package is compatible with or not
// using isCompatibleWith() method
System.out.println(
"Is this package compatible with or not:"
+ myPackage.isCompatibleWith(desiredVersion));
}
}
输出:
Package represented by myPackage:package java.io, Java Platform API Specification, version 1.8 Is this package compatible with or not:true
