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
