Thank you Chief I do appreciate

Thank you. I did check the environment variable I did try to use Java_Home and link the path properly .The only challenge is that I keep seeing temp files rather than Path in the environment variable.Please what is the proper way to configure the environment variable.

goto your c drive or where u install jdk and copy the folder with /bin ending it .

Then goto my pc and click properties and then to environment variable, in the system variable give it a name like path and paste that path u copied from your installation folder and then save.

This is just a rough explanations, i hope you get it oo , else use google bro or stackoverflow.

I am trying to make an Android app not with Android studio but another window app.Usually with Android studio when you want to build and generate you app, you do insert your keys or generate one that way you can upload it on the app store. Now when I try to generate the keys I got that error. It also does not accept keys I generate externally. I think it is a configuration problem that as to do with the jdk or jre.

Then check if you install the jdk correctly with the jre and also check for environment variable and see if you set the path appropriately.

This is a Havit HV-H2116D Stereo

I want to know if this hardware is very good at recording - I mean is the microphone very good, no humming & no deal breakers?

Thanks.

yes we can.

Hello folks, i use a high end machine with 2019 Windows 10 enterprise OS but i have noticed something for a while ,whenever i am connected to a WiFi network (my battery is always at best performance) at 100 percent battery level with the charger plugged out , there is always a quantum leap with the rate my battery drops and it has been giving me concerns cos the system is kinda pricey.

Now my question is , is my battery depreciating or that is all most system battery work under such condition??

NB: i use a HP Elitebook.

bro , what are technologies you deploy to make the game ??

If i may sire ask , when did you finish college?

Should i politicize the thread ?

The resident NL Hezbollah chief has spoken , his fecal matter and semen are all over the thread .

'Let amerika touch iran and the world will freeze' , not only did america touch iran , trump shook the the whole country.

Lati Jan 3 faa , My guy just woke up while crown prince Mohammed bin Salman has been singing :

Olorun toda awon oke igbani, iwo ni mofi ope e mi fun .

Their use to be a guy that will drop his submission on this kind of thread but not this time , why ?

Lol

In light of recent events, the killing of Iran military commander General Qassem Soleimani and US response to potential impeding strike , will trump stay in the white house beyond Jan.20 , 2021 ??

US sure have a lot of enemies but they have one thing in common, Lol.

Lol

Lol

Yeah , and revenge you will get

yeah

This is beautiful. This is a good news.

Perhaps when all Amerikan Embassies worldwide are attacked, the Washington District Criminals and her lackeys in Tel Aviv, London, Paris, Riyadh & all NATO capitals around the world will begin to get the message.

This is no longer business as usual.

My sincere prayer is for satan to push Trump into attacking Iran so that the United Snakes of Amerika can crumble quickly.

One misguided move on Iran and Iran will in effect target every oil, natural gas field, installation, refinery, ports, basically all the whole oil and gas infrastructure of the GCC countries.

The Persian Gulf will be a no-go zone and that means that overnight, 50% of the worlds total oil production and flow would cease.

Every war the Amerika has prosecuted since 1946 saw no fighting on the US mainland. About time that changed. Make 300 million Americans know what being carpet bombed feels like.

And I also expect Iran to covertly supply just THREE missiles to the Houthis in Yemen to destroy the 14mbpd salt water injection plant at Qurayyah and 80% of Saudi Crude Oil Production 8.5mbpd from the Ghawar/Khurais oil fields inland will cease.

If the price of oil increases by $70 then Russia stand to gain $70 x 365 x 14mbpd (Russian oil/gas equivalent exports) = $350 BILLION per year.

Even Nigeria will not be left out of this overnight prosperity - as she would rake in over $51Billion per year.

It's time to be proactive against the Great Amerikan Satan.

Here's a recent statement made by Iranian Commander "Amir Ali Hajizadeh", Head of the Revolutionary Guards’ Aerospace Division.

“An aircraft carrier that has at least 40 to 50 planes on it and 6,000 forces gathered within it was a serious threat for us in the past, but now it is a target and the threats have switched to opportunities,”

“If (the Americans) make a move, we will hit them in the head,”

I do not need Orunmila to tell me Russia, China, North Korea, Venezuela, Cuba & other axis of resistance are already standing by.

I leave you with a video of an Important Statement which was released by Mother Russia on December 24, 2019 (Christmas Eve).

No he did not.

Roger , also saw the same thing on his personal website.

Hi folks , to people who might know nonso or know about the gist , did he actually finish studying chemical engineering from covenant before leaving Nigeria in 2014?

Mr Zoharariel will never contribute to a thread like this

Hi folks, compliment of the season.

I am in need of a good and very affordable lavalier microphone , please anyone have with any info that might help?

Thanks.

stanliwise:
Next time you paste coding problems, please place the error messages.
Not everyone has time to run your codes especially when it has dependencies or compatibility requirements.

Affirmative sire, thanks.

Lol

crunchyDope:
just ran your code

the bug is in the "take test" method

you initialized your random questions to 10 but when you create a random question you save it to just the first index (0) because you keep initializing "count=0" over again

solution
place "int count = 0 " outside the iteration

goodluck

Thanks boss , i really appreciate.

Coding can be really crazy , after quite sometimes of drinking coffee(Java) i still made such a simple error - keep giving count value of zero after every iteration and it never crossed my mind after several attempt to debug .

Once again thanks.

lincsnuel:
Your problem lies here:

while (numbies.size() <= questions.length) {

Remove "<=" and use only "<" or use:
while (numbies.size() <= (questions.length -1) {

Remember arrays start from 0, this implies that the first Question object is assigned the value 0. Since your arraylist is 10 (i.e 0-9), then numbies should be less than questions.length

Thanks boss man , God bless.

2kaybiel:
Not readable, sorry I can't contribute.

Next time, add comments for easy reading.

Goddammit , can i reach you through other medium , walai NL has long way to go - if nairaland had special code input blueprint we won't be having this conversation.

stanliwise:
I didn't read your code sha. but once you randomize throught the questions, for each you have selected, just delete from the the array and stor it in another array.
List_of_questions
answered_questions.

use Arraylist data structure, it is more flexible.

Lol, well we've said you didn't read the code, i did utilize it anyways and you might want to take a close look at it.
