        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); 
        } 
    }

        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(); 
        }
