The println(double) method of PrintStream 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 // PrintStream println(double) method import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintStream instance
PrintStream stream
= new PrintStream(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
stream.println( 4.5 );
stream.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
} |
Output:
4.5
Program 2:
// Java program to demonstrate // PrintStream println(double) method import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintStream instance
PrintStream stream
= new PrintStream(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
stream.println( 1.65 );
stream.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
} |
Output:
1.65
