The write(String, int, int) method of PrintWriter 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 // PrintWriter write(String, int, int) method import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintWriter instance
PrintWriter 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 // PrintWriter write(String, int, int) method import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintWriter instance
PrintWriter 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
