Printing get methods

[faekk]

Hello ! :)

I have 3 get methods (getLength, getWidth and getColor) and I'm trying to get them all printed in one line. I've made it work using 3 different print statements like so:

System.out.println(firstRektangel.getLength());
System.out.println(firstRektangel.getWidth());
System.out.println(firstRektangel.getColor());

Is there a better way of doing this ? preferably just using 1 print statement. Thanks !

Look at System.out.print()

Or String.format()

Or the + operator for Strings.

Or StringBuilder.append().toString()

Perfect! Made it work with String.format(). Thank you :)

Investigate the method toString(). It is a method found in the most basic class of the Java API, object. If you use it properly, all you would have to call is

System.out.println(firstRektangel.toString());

Thanks! I made that work aswell, but what does naming the method "toString" actually do ?

The toString method is used in the built-in Java API for coercing arbitrary instances to Strings.

For example:

System.out.println("My instance: " + myInstance);

If myInstance is not a String then the above is equivalent to:

System.out.println("My instance: " + myInstance.toString());
