The reset() method of the CharArrayWriter class in Java is used to reset the buffer so that it can be used again without throwing away the already allocated buffer.
Syntax:
public void reset()
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 reset() 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());
// Resets the current stream
char_array1.reset();
// Use of size() method
System.out.println( "Size of char_array1 : "
+ char_array1.size());
}
} |
Output:
Size of char_array1 : 5 Size of char_array1 : 0
Program 2:
Java
// Java program to illustrate // the reset() 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());
// Resets the current stream
char_array1.reset();
// Use of size() method
System.out.println( "Size of char_array1 : "
+ char_array1.size());
}
} |
Output:
Size of char_array1 : 6 Size of char_array1 : 0
