Java PrintWriter print(float)方法及实例

Java中PrintWriter类的print(float)方法用于在流中打印指定的浮点值。这个浮动值被作为一个参数。

语法。

public void print(float floatValue)

参数。该方法接受一个强制性参数floatValue，它是要写入流中的浮点数值。

返回值。该方法不返回任何值。

下面的方法说明了print(float)方法的工作原理。

程序 1:

// Java program to demonstrate// PrintWriter print(float) 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 float value '4.5'            // to this stream using print() method            // This will put the floatValue in the            // stream till it is printed on the console            printr.print(4.5);              printr.flush();        }        catch (Exception e) {            System.out.println(e);        }    }}

输出:

4.5

程序2。

// Java program to demonstrate// PrintWriter print(float) 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 float value '1.65'            // to this stream using print() method            // This will put the floatValue in the            // stream till it is printed on the console            printr.print(1.65);              printr.flush();        }        catch (Exception e) {            System.out.println(e);        }    }}

输出:

1.65
