Java: Variable change
The word "variable" itself means that it can be changed. Indeed, over time within the program, the values of the variables may change.
// greeting - translated as greeting
var greeting = "Father!";
System.out.print(greeting);
System.out.print(greeting);
greeting = "Mother!";
System.out.print(greeting);
System.out.print(greeting);

The name remains the same, but inside the other data. It should be noted that when changing variables, the type of data contained in them cannot change (this is not quite the case for object-oriented programming, but for the time being we will not go into details). If a variable was assigned a string, then when compiling this assignment — even before the program was started — java associates the data type “string” with this variable, and knows that there will always be only strings, and will not let it put something else in it.
Variables are powerful, and at the same time dangerous thing. One can never be exactly sure what is written inside it without analyzing the code that is in front of the variable. This is exactly what the developers are doing during debugging, when they are trying to figure out why the program is not working or is not working as intended.
Instructions
The code defines a variable with the value 'Brienna'. Redefine the value of this variable and assign it the same line, but upside down.
The exercise doesn't pass checking. What to do? 😶
If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:
- Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.
In my environment the code works, but not here 🤨
Tests are designed so that they test the solution in different ways and against different data. Often the solution works with one kind of input data but doesn't work with others. Check the «Tests» tab to figure this out, you can find hints at the error output.
My code is different from the teacher's one 🤔
It's fine. 🙆 One task in programming can be solved in many different ways. If your code passed all tests, it complies with the task conditions.
In some rare cases, the solution may be adjusted to the tests, but this can be seen immediately.
I've read the lessons but nothing is clear 🙄
It's hard to make educational materials that will suit everyone. We do our best but there is always something to improve. If you see a material that is not clear to you, describe the problem in “Discussions”. It will be great if you'll write unclear points in the question form. Usually, we need a few days for corrections.
By the way, you can participate in courses improvement. There is a link below to the lessons course code which you can edit right in your browser.
