How to println a string and variable within the same parameters

I am writing some code right now and I haven't done this in a while, how would I use the println function to write both a string and a variable?

I tried the following:

System.out.println("randomtext"var);

and 

System.out.println("randomtext",var);

Neither of those seemed to work, what am I doing wrong? How do I do this?

You either need to use + to concatenate, or use String.format to format a string or similar.

The easiest is to do concatenation:

System.out.println("randomtext" + var);

Some people often use System.out.printf which works the same way as String.format if you have a big messy string you want to concatenate:

System.out.printf("This is %s lot of information about %d and %s", var, integer, stringVar);

When using String.format the most important formatters you need to know is %s for Strings, %f for floating-point numbers, %d for integers.

More information about how to use String.format can be found in the documentation about Formatter.

You can concatenate the two strings together; the overloaded println methods take at most one parameter.

System.out.println("randomtext" + var);
