I cant change a final var, but... why this code compiles?

It prints: xyz, so... you cant change the reference of the variable, but you can change the value if you dont touch the reference?


arr = {"a","b","c"} ------ > String[] Line #1


arr = {"x","b","c"} ------ > String[] Line #2 // same reference of String[]


arr = {"x","y","c"} ------ > String[] Line #3 // same reference of String[]


arr = {"x","y","z"} ------ > String[] Line #2 // same reference of String[]


The reference never change. Am I right?

next code shows the same, not with arrays:





x = 1 ------ > StringBuilder Line #1
a = x
x = 12



so it prints:
a: 12
x: 12

So, the question is: Can We change the value of the var if We dont change the reference?

Well, that happens often, because:

1) They says "im an Architect", the people who hire arent experts so " im Architects, 27 years, 3 years experience and i ride motorcycles" they will be like "WOW!"
2) they can manage projects but cant develop. So, theyre more like project leaders
3) They are like doogie howser

You need a lot of experience, knowledge about almost everything, infrastructure, weak points, skills, how to fix problems without ask, help people, be rational, work team, work under pressure.

I know many guys who say, "im an arch", but they arent."
The organization depends too, if i have a company, i need money. I prefer to sell archs than programmers(outsourcing)

Work hard, be honest with yourself. And you could become a good architect

I guess, FOR as SWITCH must have predefined variables on the stack to play(in switch constant values assigned on the declaration)





Java tutorial says:


but it's more like,



it prints

Thanks to all!
Hi,


Can you help me here?


this one, compilation fails

this one, infinite loop.


If the condition is false, then the for is useless right? why the unreachable code?


Thanks in advice

once i had a similar problem.
I fixed saving the rs.getString(1) into a variable and just calling the variable.


Hope this help you.
