PrintWriter println(double) method in Java with Examples

The println(double) method of PrintWriter Class in Java is used to print the specified double value on the stream and then break the line. This double value is taken as a parameter.

Syntax:

public void println(double doubleValue)

Parameters: This method accepts a mandatory parameter doubleValue which is the double value to be written on the stream.

Return Value: This method do not returns any value.

Below methods illustrates the working of println(double) method:

Program 1:

// Java program to demonstrate
// PrintWriter println(double) method

import java.io.*;

class GFG {
    public static void main(String[] args)
    {

        try {

            // Create a PrintWriter instance
            PrintWriter printr
                = new PrintWriter(System.out);

            // Print the double value '4.5'
            // to this stream using println() method
            // This will put the doubleValue in the
            // stream till it is printed on the console
            printr.println(4.5);

            printr.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

4.5

Program 2:

// Java program to demonstrate
// PrintWriter println(double) method

import java.io.*;

class GFG {
    public static void main(String[] args)
    {

        try {

            // Create a PrintWriter instance
            PrintWriter printr
                = new PrintWriter(System.out);

            // Print the double value '1.65'
            // to this stream using println() method
            // This will put the doubleValue in the
            // stream till it is printed on the console
            printr.println(1.65);

            printr.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

1.65
