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