程序 1:

// Java program to demonstrate// PrintStream print(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 print() method            // This will put the doubleValue in the            // stream till it is printed on the console            stream.print(4.5);              stream.flush();        }        catch (Exception e) {            System.out.println(e);        }    }}

输出:

4.5

程序2。

// Java program to demonstrate// PrintStream print(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 print() method            // This will put the doubleValue in the            // stream till it is printed on the console            stream.print(1.65);              stream.flush();        }        catch (Exception e) {            System.out.println(e);        }    }}

输出:
