The getClass() method of Writer Class in Java is used to get the parent Class of this Writer instance. This method does not accept any parameter and returns the required Class details.
Syntax of getClass() method
public final Class String getClass()
Calling of the getClass() method
object_name.getClass();
Parameters: This method accepts does not accepts any parameter.
Return Value: This method returns the Class details which is the parent Class of the Writer instance.
Note: The Object class is the superclass for all the classes in Java. Hence, every class can implement the getClass() method.
Examples of the Writer getClass() method
The below methods illustrate the working of the getClass() method:
Example 1
Java
// Java program to demonstrate// Writer getClass() methodimport java.io.*;// Driver Classclass GFG { // main function 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 Class details using getClass() System.out.println("Parent Class: " + writer.getClass()); } catch (Exception e) { System.out.println(e); } }} |
Output
Parent Class: class java.io.PrintWriter
Example 2
Java
// Java program to demonstrate// Writer getClass() methodimport java.io.*;// Driver Classclass GFG { // main function public static void main(String[] args) { try { // Create a Writer instance Writer writer = new OutputStreamWriter(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 Class details using getClass() System.out.println("Parent Class: " + writer.getClass()); } catch (Exception e) { System.out.println(e); } }} |
Output
Parent Class: class java.io.OutputStreamWriter
