The size() method of the CharArrayWriter class in Java is used to get the current size of the buffer.
Syntax:
public int size()
Parameters: This method does not accept any parameter.
Return Value: This method returns an integer value which signifies the current size of the buffer.
Below program illustrate the above method:
Program 1:
// Java program to illustrate // the size() method import java.io.*; public class GFG { public static void main(String[] args) throws IOException { // Initailizing the character array char [] geek = { 'G' , 'E' , 'E' , 'K' , 'S' }; // Initailizing 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()); } } |
Size of char_array1 : 5
Program 2:
// Java program to illustrate // the size() method import java.io.*; public class GFG { public static void main(String[] args) throws IOException { // Initailizing the character array char [] geek = { 'G' , 'O' , 'P' , 'A' , 'L' , 'L' }; // Initailizing 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()); } } |
Size of char_array1 : 6
