The append(CharSequence, int, int) method of StringWriter Class in Java is used to append a specified portion of the specified charSequence on the writer. This charSequence is taken as a parameter. The starting index and ending index to be written are also taken as parameters.
Syntax:
public void append(CharSequence charSequence, int startingIndex, int endingIndex)
Parameters: This method accepts three mandatory parameters:
- charSequence which is the charSequence to be written in the Stream.
- startingIndex which is the starting index from which the portion of character is to taken.
- endingIndex which is the ending index to be written on the writer.
Return Value: This method does not returns any value.
Below programs illustrates the working of append(CharSequence, int, int) method:
Program 1:
// Java program to demonstrate// StringWriter append(CharSequence, int, int) method import java.io.*; class GFG { public static void main(String[] args) { try { // Create a StringWriter instance StringWriter writer = new StringWriter(); // Get the charSequence // to be written in the writer CharSequence charSequence = "GeeksForGeeks"; // Get the starting index int startingIndex = 0; // Get the length of char int endingIndex = 5; // Write the portion of the charSequence // to this writer using append() method // This will put the charSequence in the writer // till it is printed on the console writer.append(charSequence, startingIndex, endingIndex); System.out.println(writer.toString()); } catch (Exception e) { System.out.println(e); } }} |
Output:
Geeks
Program 2:
// Java program to demonstrate// StringWriter append(CharSequence, int, int) method import java.io.*; class GFG { public static void main(String[] args) { try { // Create a StringWriter instance StringWriter writer = new StringWriter(); // Get the charSequence // to be written in the writer CharSequence charSequence = "GFG"; // Get the starting index int startingIndex = 2; // Get the length of char int endingIndex = 3; // Write the portion of the charSequence // to this writer using append() method // This will put the charSequence in the writer // till it is printed on the console writer.append(charSequence, startingIndex, endingIndex); System.out.println(writer.toString()); } catch (Exception e) { System.out.println(e); } }} |
Output:
G
