Thread: Learning about formatting your output

This program should be an example of how Java lets you format numbers and strings. First you will need to study Java's formatting facilities, and then write a program which shows real numbers being printed with different widths and precisions. Show how the result of printing 8/3 [eight divided by three] can be printed in different ways (different widths and different precisions). Show how we can left-justify a column of several rows of names, and how we can right -justify them. Show how we can make a column of decimal numbers line up on their decimal points. You have a lot of latitude in this program and can be creative. Experiment. A good program will show that its creator has studied and understood all the ways that data can be formatted when printed.

my question is that i didn't understand the question i just posted.

It wasn't a question. It was mostly a list of things you were told to do.

Don't be put off by the detail - alignment, precision etc - the most important thing you were told to do is "study Java's formatting facilities". If you have a textbook, consult it. Certainly read the API documentation.

What class or classes are you going to try using? Once you have that sorted out you can begin thinking about each of the formatting styles you were asked to illustrate.

[Edit] And post if you get stuck! As you've realised, nobody here is going to write the code for you (and you haven't asked for that). So it is really important you say precisely what you are going to do (what classes) and where you're at (what code) And ask questions that are as specific as possible (What does "alignment" mean?, What does the following runtime exception mean? etc)
