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
