ok its working now butr it dsiplays 50000.0   <-- thats odd why wont is show 50000.00   ???

[Select]

// A programs contains the following method:
//public static void display(int arg1, double arg2, char arg3)
//{
// System.out.println("The values are " + arg1 + ", " +
//arg2 + ", and " + arg3);
//}
//Write a statement that calls this method and passes the following varibles as arguements:
//char initial = 'T';
//int age = 25;
//double income = 50000.00


public class PassArg4
{
   public static void main(String[] args)
   {
    
  char initial = 'T';
     int age = 25;
     double income=50000.00;
     display(age, income, initial);

    
     }


// A programs contains the following method:
public static void display(int arg1, double arg2, char arg3)
{
System.out.println("The values are " + arg1 + ", " +
arg2 + " ,  and " + arg3);
}
// Write a statement that calls this method and passes the following varibles as arguments:
// char initial = 'T';
// int age = 25;
// double income = 50000.00
}

Why does it just show 50000.0       <------?
instead of 50000.00    <-- everything else is right
