import java.io.*;
public class GFG {
public static void main(String[] args)
throws IOException
{
char [] geek = { 'G' , 'E' , 'E' , 'K' , 'S' };
CharArrayWriter char_array1
= new CharArrayWriter();
for ( int c = 72 ; c < 77 ; c++) {
char_array1.write(c);
}
System.out.println( "\nSize of char_array1 : "
+ char_array1.size());
char_array1.reset();
System.out.println( "Size of char_array1 : "
+ char_array1.size());
}
}

for ( int c = 72 ; c < 78 ; c++) {
char_array1.write(c);
}
System.out.println( "\nSize of char_array1 : "
