Description
The java.io.CharArrayWriter.append(CharSequence csq, int start, int end) method appends a portion of the specified character sequence to this writer.
Declaration
Following is the declaration for java.io.CharArrayWriter.append(CharSequence csq, int start, int end) method −
public CharArrayWriter append(CharSequence csq, int start, int end)
Parameters
csq − The character sequence to be appended. If the character sequence is null, the writer is appended with 4 characters 'null'.
start − The index of the first character in the portion
end − The index of the character following the end of the subsequence
Return Value
This CharArrayWriter
Exception
IndexOutOfBoundsException − If end is greater than sequence's length, start is greater than end, or start or end are negative.
Example
The following example shows the usage of java.io.CharArrayWriter.append(CharSequence csq, int start, int end) method.
package com.tutorialspoint; import java.io.CharArrayWriter; public class CharArrayWriterDemo { public static void main(String[] args) { CharArrayWriter chw = null; try { // create character array writer chw = new CharArrayWriter(); // declare character sequence CharSequence csq = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; // append character sequence to the writer chw.append(csq, 2, 5); // prints out the character sequences System.out.println(chw.toString()); } catch(Exception e) { // for any error e.printStackTrace(); } finally { // releases all system resources from writer if(chw!=null) chw.close(); } } }
Let us compile and run the above program, this will produce the following result −
