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); } } } |
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); } } } |
1.65
