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
// Java program to illustrate // the size() method import 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());
}
} |
Output:
Size of char_array1 : 5
Program 2:
Java
// Java program to illustrate // the size() method import 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());
}
} |
Output:
Size of char_array1 : 6
