Hopefully I am understanding you correctly but this will probably help...

java

// obtaining mass in kg
mass = input.readDouble ();

// Assuming that mass is defined as a Double data type
System.out.print("mass of " + object + "= " + mass.toString());


Here we fetch the mass from the user and then display it in the print statement by calling its toString() function. This makes it a string for printing.

If this is not what you were after, you might want to clarify further. smile.gif

imagine if it were on paper and you had to fill in the blank, so question is:
Mass of object = _____ kg
the blank would be for the user input and the kg would appear behind that. yes it is a double btw.

If you just want kg to be outputted after the mass, i cant see where your input for your mass is inputted, but the output would be
CODE
System.out.print(" (kg) mass of " + object + "= " + mass + "Kg");


Just output the kg as a string after you output the mass.

I think what you're trying to do is impossible, because after user types number of kilograms, he presses ENTER key (new line).
