The hashCode() method of Writer Class in Java is used to get the HashCode value of this Writer instance. This method does not accepts any parameter and returns the required int value.
Syntax:
public int hashCode()
Parameters: This method accepts does not accepts any parameter.
Return Value: This method returns a int value which is the HashCode value of the Writer instance.
Below methods illustrates the working of hashCode() method:
Program 1:
// Java program to demonstrate// Writer hashCode() method import java.io.*; class GFG { public static void main(String[] args) { try { // Create a Writer instance Writer writer = new PrintWriter(System.out); // Get the String // to be written in the stream String string = "GeeksForGeeks"; // Write the string // to this writer using write() method writer.write(string); // Get the HashCode value using hashCode() System.out.println("HashCode value: " + writer.hashCode()); } catch (Exception e) { System.out.println(e); } }} |
Output:
HashCode value: 589431969
Program 2:
// Java program to demonstrate// Writer hashCode() method import java.io.*; class GFG { public static void main(String[] args) { try { // Create a Writer instance Writer writer = new PrintWriter(System.out); // Get the String // to be written in the stream String string = "GFG"; // Write the string // to this writer using write() method writer.write(string); // Get the HashCode value using hashCode() System.out.println("HashCode value: " + writer.hashCode()); } catch (Exception e) { System.out.println(e); } }} |
Output:
HashCode value: 589431969
