The write(String, int, int) method of Writer Class in Java is used to write a specified portion of the specified String on the stream. This String is taken as a parameter. The starting index and length of String to be written are also taken as parameters.
Syntax:
public void write(String string, int startingIndex, int lengthOfstring)
Parameters: This method accepts three mandatory parameters:
- string which is the String to be written in the Stream.
- startingIndex which is the starting index from which the portion of character is to taken.
- lengthOfstring which is the length of String to be written on the stream.
Return Value: This method do not returns any value.
Below methods illustrates the working of write(String, int, int) method:
Program 1:
// Java program to demonstrate// Writer write(String, 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 String // to be written in the stream String string = "GeeksForGeeks"; // Get the starting index int startingIndex = 0; // Get the length of char int lengthOfstring = 5; // Write the portion of the string // to this writer using write() method // This will put the string in the stream // till it is printed on the console writer.write(string, startingIndex, lengthOfstring); writer.flush(); } catch (Exception e) { System.out.println(e); } }} |
Output:
Geeks
Program 2:
// Java program to demonstrate// Writer write(String, 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 String // to be written in the stream String string = "GFG"; // Get the starting index int startingIndex = 2; // Get the length of char int lengthOfstring = 1; // Write the portion of the string // to this writer using write() method // This will put the string in the stream // till it is printed on the console writer.write(string, startingIndex, lengthOfstring); writer.flush(); } catch (Exception e) { System.out.println(e); } }} |
Output:
G
