write(char[], int, int): This method is available in the java.io.Writer class of Java.
Syntax:
void java.io.Writer.write(char[] cbuf, int off, int len) throws IOException
This method takes three arguments. This method writes a portion of an array of characters.
Parameters: Three parameters are required for this method.
cbuf: Array of characters.
off: Offset from which to start writing characters.
len: Number of characters to write.
Returns: NA
Throws:
1. IndexOutOfBoundsException - Implementations should throw this exception if off is negative, or len is negative, or off + len is negative or greater than the length of the given array.
2. IOException - If an I/O error occurs
Approach 1: When no exception
Java
import java.io.IOException;import java.io.StringWriter;import java.io.Writer;public class Writerwrite4 {public static void main(String[] args) throws IOException {Writer writer = new StringWriter();char cbuf[] = { 'a', 'b', 'c', 'd', 'e' };int off = 0, len = 3;writer.write(cbuf, off, len);System.out.println("Successfully writes");writer.close();}}
Output:
Successfully writes
Approach 2: IndexOutOfBoundsException
Java
package com.Writer;import java.io.IOException;import java.io.StringWriter;import java.io.Writer;public class Writerwrite4 {public static void main(String[] args) throws IOException {Writer writer = new StringWriter();char cbuf[] = { 'a', 'b', 'c', 'd', 'e' };int off = 0, len = 13;writer.write(cbuf, off, len);System.out.println("Successfully writes");writer.close();}}
Output:
Exception in thread "main" java.lang.IndexOutOfBoundsException at java.base/java.io.StringWriter.write(StringWriter.java:95) at com.Writer.Writerwrite4.main(Writerwrite4.java:14)
Approach 3: IOException
Java
package com.Writer;import java.io.IOException;import java.io.PipedWriter;import java.io.Writer;public class Writerwrite4 {public static void main(String[] args) throws IOException {Writer writer = new PipedWriter();char cbuf[] = { 'a', 'b', 'c', 'd', 'e' };int off = 0, len = 3;writer.write(cbuf, off, len);System.out.println("Successfully writes");writer.close();}}
Output:
Exception in thread "main" java.io.IOException: Pipe not connected at java.base/java.io.PipedWriter.write(PipedWriter.java:152) at com.Writer.Writerwrite4.main(Writerwrite4.java:14)
