Java: Variables and Concatenation

To consolidate the previous topic, try using variables with concatenation. Syntactically nothing changes: we can concatenate (glue) two lines:

var what = "Kings" + "road";
System.out.print(what); // => "Kingsroad"

... which means we can concatenate a string and one variable in which the string is written:

var first = "Kings";
var what = first + "road";

System.out.print(what); // => "Kingsroad"

... and even concatenate two variables in which the lines are written:

var first = "Kings";
var last = "road";

var what = first + last;
System.out.print(what); // => "Kingsroad"

Instructions

Sites are constantly sending emails to their users. A typical task is to make an automatic sending of a personal letter, where the user name is in the header. If somewhere in the site base the name of the person is stored as a string, then the task of generating the header is reduced to concatenation: for example, you need to glue the string Hello with the string where the name is written.

Write a program that will generate the header and body of the letter, using the ready-made variables, and display the resulting lines on the screen.

For the title, use the variables firstName and greeting, a comma and an exclamation point. Display it in the correct order.

For the body of the letter, use the variables info and intro, with the second sentence should be on a new line.

The result on the screen will look like this:

Hello, Joffrey!
Here is an important information about your account security.
We couldn't verify you mother's maiden name.

Perform the job using only two System.out.print.

Tips

• Consider with which line and in what order you need to glue the modules.variables together in order to get such a two-line output of the letter body.

• Remember that you can create a string that contains only the control sequence \n.
