Parameters: This method accepts a mandatory parameter charValue which is the char value to be appended on the writer.
Return Value: This method does not returns any value.
Below programs illustrates the working of append(char) method:
Program 1:
// Java program to demonstrate// StringWriter append(char) method import java.io.*; class GFG { public static void main(String[] args) { try { // Create a StringWriter instance StringWriter writer = new StringWriter(); // Append the char value 'A' // to this writer using append() method // This will put the charValue in the // writer till it is appended on the console writer.append('A'); System.out.println(writer.toString()); } catch (Exception e) { System.out.println(e); } }} |
Output:
A
Program 2:
// Java program to demonstrate// StringWriter append(char) method import java.io.*; class GFG { public static void main(String[] args) { try { // Create a StringWriter instance StringWriter writer = new StringWriter(); // Append the char value 'G' // to this writer using append() method // This will put the charValue in the // writer till it is appended on the console writer.append('G'); System.out.println(writer.toString()); } catch (Exception e) { System.out.println(e); } }} |
Output:
G
