The flush() method of the CharArrayWriter class in Java is used to flush the stream.
Syntax:
public void flush()
Parameters: This method does not accept any parameter.
Return Value: This method does not returns anything.
Below program illustrate the above method:
Program 1:
Java
// Java program to illustrate// the flush() methodimport java.io.*;public class GFG { public static void main(String[] args) throws IOException { // Initializing the character array char[] geek = { 'G', 'E', 'E', 'K', 'S' }; // Initializing the CharArrayWriter CharArrayWriter char_array1 = new CharArrayWriter(); for (int c = 72; c < 77; c++) { // Use of write(int char) // Writer int value to the Writer char_array1.write(c); } // Use of size() method System.out.println("\nSize of char_array1 : " + char_array1.size()); // Flushes the current stream char_array1.flush(); }} |
Output:
Size of char_array1 : 5
Program 2:
Java
// Java program to illustrate// the flush() methodimport java.io.*;public class GFG { public static void main(String[] args) throws IOException { // Initializing the character array char[] geek = { 'G', 'O', 'P', 'A', 'L', 'L' }; // Initializing the CharArrayWriter CharArrayWriter char_array1 = new CharArrayWriter(); for (int c = 72; c < 78; c++) { // Use of write(int char) // Writer int value to the Writer char_array1.write(c); } // Use of size() method System.out.println("\nSize of char_array1 : " + char_array1.size()); // Flushes the current stream char_array1.flush(); }} |
Output:
Size of char_array1 : 6
