Use java to write an application to convert decimal number to IEEE-754 Single Pr

Question

Use java to write an application to convert decimal number to IEEE-754 Single Precision Floating-Point Representation (32-bit) and IEEE-754 Double Precision Floating-Point Representation (64-bit) and convert back to decimal. Use GUI as user interface asking the user for decimal number and the program will output the result.

Specification The IEEE-754 single precision floating point standard uses an 8-bit exponent (with a bias of 127) and a 23-bit significand. The IEEE-754 double precision standard uses an 11-bit exponent (with a bias of 1023) and a 52-bit significand.

This is what I have so far. I am new to using GUI so I don't really know how to do it.

import java.util.Scanner;

public class conversionS

{

   private static Scanner scanInput;

   public static void main(String[]args)

   {

      scanInput = new Scanner(System.in);

      double decimalNum;

      int valueBit;

      String stringOfBits;

      System.out.println("Please enter the decimal that needs to convert in single precision floating point");

      decimalNum = scanInput.nextInt();

      float f = (float)decimalNum;

      valueBit = Float.floatToIntBits(f);

      stringOfBits = Integer.toBinaryString(valueBit);

      System.out.println("Single precision floating point:" + stringOfBits);

      System.out.println("Please enter the decimal that needs to convert in double precision floating point");

      decimalNum = scanInput.nextInt();

       stringOfBits = Long.toString(Double.doubleToLongBits(decimalNum), 2);

      System.out.println("double precision floating point:" + stringOfBits);

   }

}

Explanation / Answer

import java.lang.Math; // header stuff MUST go above the first class

// our main class becomes a file but the main method is still found
import java.util.Scanner;
public class conversionS
{
private static Scanner scanInput;

public static void main(String[]args)
{
scanInput = new Scanner(System.in);
double decimalNum;
int valueBit;
String stringOfBits;
  
System.out.println("Please enter the decimal that needs to convert in single precision floating point");
  
decimalNum = scanInput.nextInt();
float f = (float)decimalNum;
valueBit = Float.floatToIntBits(f);
stringOfBits = Integer.toString(valueBit, 2);
System.out.println("Single precision floating point:" + stringOfBits);
  
System.out.println("Please enter the decimal that needs to convert in double precision floating point");
  
decimalNum = scanInput.nextInt();
stringOfBits = Double.toString(Double.doubleToLongBits(decimalNum), 2);
System.out.println("double precision floating point:" + stringOfBits);
  
}
}
