The hashCode() method of java.lang.Package class is used to get the hashCode value of this package instance. The method returns the hashCode value as an integer value.
Syntax:
public int hashCode()
Parameter: This method does not accepts any parameter.
Return Value: This method returns the hashCode value as an integer value.
Below programs demonstrate the hashCode() method.
Example 1:
Java
// Java program to demonstrate// hashCode() 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()); // get the hashCode value of this package // using hashCode() method System.out.println( "hashCode value: " + myPackage.hashCode()); }} |
Output:
Package represented by myPackage: package java.lang, Java Platform API Specification, version 1.8 hashCode value: -888658374
Example 2:
Java
// Java program to demonstrate// hashCode() 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()); // get the hashCode value of this package // using hashCode() method System.out.println( "hashCode value: " + myPackage.hashCode()); }} |
Output:
Package represented by myPackage: package java.io, Java Platform API Specification, version 1.8 hashCode value: -1819917198
