    Default Display program

    Hey,
    I am trying to have the user input an integer, a float, and a double. For example:

    Input the Integer: 7
    Input float: 7
    Input the double: 66.4

    And then display the following output:

    THe integer is: 7 The float is: 7.0 The double is: 66.4

    My code runs fine, however it only produces the output for an integer, and leaves the float / double as 0.0 :

    THe integer is: 7 The float is: 0.0 The double is: 0.0

    I have 2 separate files "Show.java" and "UtilShow.java". The code for both of them is below:

    Show.java file
    Java Code:
    public class Show
    {
    private int Integer;
    private float Float;
    private double Double;
     
    public Show (int inTeger ) 
    {
    Integer = inTeger;
    }
     
    public Show (float fLoat)
    {
    Float = fLoat;
    }
     
    public Show (double douBle)
    {
     Double = douBle;	
    }
     
    public void Display()
    {
    System.out.println("THe integer is: " +Integer + " The float is: " +Float + " The double is: " +Double);
    } 
     
    }

    UtilShow.java file
    Java Code:
    import java.io.*;
    public class UtilShow{
     
    public static void main(String[] args)
    {
    try {
    InputStreamReader isr = new InputStreamReader(System.in);
    BufferedReader br = new BufferedReader(isr);
    System.out.print("Input the Integer: ");
    Show intone = new Show(Integer.parseInt(br.readLine()));
    System.out.print("Input float: ");
    Show fone = new Show(Float.parseFloat(br.readLine()));
    System.out.print("Input the double: ");
    Show done = new Show(Double.parseDouble(br.readLine()));
     
    intone.Display();
     
    }
    catch(Exception e) {}
    }
    }

    Can anybody please help me out? Thanks alot!

    Default

    Right now you are creating a new instance of the class Show for each variable.
    Java Code:
    Show intone = new Show(Integer.parseInt(br.readLine()));
    intone.Display();
    So you are only displaying intone.

    Java Code:
    public Show (int inTeger, double dblVal, float  fVal) {..}
