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);
}
}

Program 2:
// 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 = "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 stream
// till it is printed on the console
writer.append(charSequence,
startingIndex,
endingIndex);
writer.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
