Package isCompatibleWith() method in Java with Examples
The isCompatibleWith() method of java.lang.Package class is used to check if this package’s specification version is compatible with the specified version or not. The method returns the result as a boolean value.
Syntax:
public boolean isCompatibleWith(String desiredVersion)
Parameter: This method accepts a parameter desiredVersion which is the version to be checked for compatibility.
Return Value: This method returns the result as a boolean value.
Below programs demonstrate the isCompatibleWith() method.
Example 1:
Java
// Java program to demonstrate// isCompatibleWith() methodpublic 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)); }} |
Output:
Package represented by myPackage: package java.lang, Java Platform API Specification, version 1.8 Is this package compatible with or not: true
Example 2:
Java
// Java program to demonstrate// isCompatibleWith() methodpublic 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)); }} |
Output:
Package represented by myPackage: package java.io, Java Platform API Specification, version 1.8 Is this package compatible with or not: true
