import java.io.*; 
  
class GFG { 
    public static void main(String[] args) 
    { 
  
        try { 
  
            // Create a PrintStream instance 
            PrintStream stream 
                = new PrintStream(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 
            stream.print(4.5); 
  
            stream.flush(); 
        } 
        catch (Exception e) { 
            System.out.println(e); 
        } 
    } 
}

输出：

4.5

示例2:

import java.io.*; 
  
class GFG { 
    public static void main(String[] args) 
    { 
  
        try { 
  
            // Create a PrintStream instance 
            PrintStream stream 
                = new PrintStream(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 
            stream.print(1.65); 
  
            stream.flush(); 
        } 
        catch (Exception e) {
