The Java.io.Writer.equals(Object obj) method of Writer class in Java is used to check whether the two instances of Writer are equal or not. It returns a boolean stating whether they are equal or not.
Signature:
public boolean equals(Writer second_Writer)
Syntax:
first_Writer.equals(second_Writer)
Parameters: This method accepts a mandatory parameter second_Writer which refers to the second Writer to be compared to the first Writer.
Return value: The method returns true if the equality holds and both the objects and Writer are equal else it returns false.
Below programs are used to illustrate the working of the java.io.Writer.elements() method:
Program 1:
// Java code to illustrate the equals() method import java.io.*; public class Writer_Demo { public static void main(String[] args) { try { // Creating an empty Writer Writer writer1 = new PrintWriter(System.out); // Inserting elements into the Writer writer1.write("GeeksForGeeks"); // Displaying the Writer System.out.println("Writer 1: " + writer1.toString()); // Creating an empty Writer Writer writer2 = new PrintWriter(System.out); // Inserting elements into the Writer writer2.write("GFG"); // Displaying the Writer System.out.println("Writer 2: " + writer2.toString()); System.out.println("Are both of them equal? " + writer1.equals(writer2)); } catch (Exception e) { System.out.println(e); } }} |
Output:
Writer 1: java.io.PrintWriter@232204a1 Writer 2: java.io.PrintWriter@4aa298b7 Are both of them equal? false
Program 2:
// Java code to illustrate the equals() method import java.io.*; public class Writer_Demo { public static void main(String[] args) { try { // Creating an empty Writer Writer writer1 = new PrintWriter(System.out); // Inserting elements into the Writer writer1.write("GFG"); // Displaying the Writer System.out.println("Writer 1: " + writer1.toString()); // Creating an empty Writer Writer writer2 = new PrintWriter(System.out); // Inserting elements into the Writer writer2.write("GFG"); // Displaying the Writer System.out.println("Writer 2: " + writer2.toString()); System.out.println("Are both of them equal? " + writer1.equals(writer2)); } catch (Exception e) { System.out.println(e); } }} |
Output:
Writer 1: java.io.PrintWriter@232204a1 Writer 2: java.io.PrintWriter@4aa298b7 Are both of them equal? false
