31 Jan, 2019
The append(CharSequence, int, int) method of PrintWriter Class in Java is used to append a specified portion of the specified charSequence on the stream. 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 stream.
Return Value: This method do not returns any value.
Below methods illustrates the working of append(CharSequence, int, int) method:
Program 1:
// Java program to demonstrate// PrintWriter append(CharSequence, int, int) method  import java.io.*;  class GFG {    public static void main(String[] args)    {          try {              // Create a PrintWriter instance            PrintWriter writer                = new PrintWriter(System.out);              // Get the charSequence            // to be written in the stream            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 stream            // till it is printed on the console            writer.append(charSequence,                          startingIndex,                          endingIndex);              writer.flush();        }        catch (Exception e) {            System.out.println(e);        }    }}
