The write(char[], int, int) method of Writer Class in Java is used to write a specified portion of the specified character array on the writer. This character array is taken as a parameter. The starting index and length of characters to be written are also taken as parameters.
Syntax:
Parameters: This method accepts three mandatory parameters:
Return Value: This method do not returns any value.
Below methods illustrates the working of write(char[], int, int) method:
Program 1:
Java
Java
Syntax:
public void write(char[] charArray, int startingIndex, int lengthOfCharArray)
Parameters: This method accepts three mandatory parameters:
- charArray which is the character array to be written in the writer.
- startingIndex which is the starting index from which the portion of character is to taken.
- lengthOfCharArray which is the length of characters to be written on the writer.
Return Value: This method do not returns any value.
Below methods illustrates the working of write(char[], int, int) method:
Program 1:
// Java program to demonstrate
// Writer write(char[], int, int) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a Writer instance
Writer writer
= new PrintWriter(System.out);
// Get the character array
// to be written in the writer
char[] charArray = { 65, 66, 67 };
// Get the starting index
int startingIndex = 0;
// Get the length of char
int lengthOfCharArray = 1;
// Write the portion of the charArray
// to this writer using write() method
// This will put the charArray in the writer
// till it is printed on the console
writer.write(charArray,
startingIndex,
lengthOfCharArray);
writer.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
