The close() method of Writer Class in Java is used to close the writer. Closing a writer deallocates any value in it or any resources associated with it. The Writer instance once closed won’t work. Also a Writer instance once closed cannot be closed again.
Syntax:
public void close()
Parameters: This method do not accepts any parameter.
Return Value: This method do not returns any value. It just closes the Stream.
Below methods illustrates the working of close() method:
Program 1:
// Java program to demonstrate// Writer close() method import java.io.*; class GFG { public static void main(String[] args) { // The string to be written in the Stream String str = "GeeksForGeeks"; try { // Create a Writer instance Writer writer = new PrintWriter(System.out); // Write the above string to this writer // This will put the string in the writer // till it is printed on the console writer.write(str); // Now close the writer // using close() method writer.close(); } catch (Exception e) { System.out.println(e); } }} |
Output:
GeeksForGeeks
Program 2:
// Java program to demonstrate// Writer close() method import java.io.*; class GFG { public static void main(String[] args) { try { // Create a Writer instance Writer writer = new PrintWriter(System.out); // Write the char to this writer // This will put the char in the writer // till it is printed on the console writer.write(65); // Now close the writer // using close() method writer.close(); } catch (Exception e) { System.out.println(e); } }} |
Output:
A
