Android – Convert arrayList to String []

Bom dia pessoal, preciso converter um ArrayList para uma String[ ].

Não consegui fazer funcionar. Somente me retorna uma string gigante. Segue meu código

public List<Item> geral(){     buscaLatLong();     List<String> nomes = new ArrayList<String>();     String[] namesArr = nomes.toArray(new String[resuladoLista.size()]);      List<Item> item = new ArrayList<>();     String listagem[] = namesArr;        for (int i = 0; i<listagem.length; i++){         Item item = new Item();         item.setNome(listagem[i]);         item.setNum(String.valueOf(i+1));         itemList.add(item);     }      return itemList; }

fiz um teste com uma string fixa no formato abaixo funcionou perfeitamente

String listagem[] = {“Teste1”, “Teste2”, “Teste3”, “Teste4”};

o resultado lista está como private static ArrayList resuladoLista; Como posso converter o meu resuladoLista para uma string idêntica ao listagem[]?

convert youtube audio to wav for linux without ffmpeg or avconv

Is there a simple command-line utility for unix available to use to convert an .m4a audio file or .webm file (that I can generate from youtube-dl) to a wave (.wav) file?

I tried ffmpeg and it gives me errors when I tried converting to any output format and it also creates zero-byte files.

I also don’t have avconv but when I looked at its documentation online I think it wants to install the same libraries ffmpeg already installed.

But rather than installing an elaborate package (as I am low on disk space), isn’t there a simple utility that can do this task for unix?

Assume we have an algorithm HC for HAMILTONIAN CIRCUIT. How is it possible to convert the HC algorithm to an algorithm HP for HAMILTONIAN PATH?

My understanding is that I have to use the algorithm for Hamiltonian Circuit to help solve the Hamiltonian Path problem.

My understanding is that we have to perform a reduction from Hamiltonian Path—> Hamiltonian Circuit (since we have an alg for Hamiltonian Circuit the reduction should be from Ham path—> Ham circuit)

But in contrast, the question says CONVERT the Ham Circuit algorithm to an algorithm to an algorithm of HP. Does this imply that the Ham Circuit problem should be reduced to the Ham Path problem?

Any guidance/feedback greatly appreciated.

What is an efficient method to convert Windows MS Access database files, code, forms, etc. to Mac FileMaker Pro

As much as possible, I need to convert Windows Access forms (entry screens, reports), tables and code to FileMaker Pro. The databases need to be brought over to Mac from an older Windows computer and updated going forward.

Note: A similar question was asked many years back with most recent updates in 2014. As much time has passed, I am checking for possible new information. How to port an Access database to the Mac?

Bash convert string to integer

I am new at bash scripting, I need to write a script capable of taking a file with a given text (written numbers and arithmetic operators) and transform these words into integers and ex: +, -, *, %.

The example that I have is a file with the following text : one two three plus nine eight seven. The script needs to change these words and transform them to 123 + 987, then printing the result 1110.

So far I have this, but I am not sure how to compare each word in the file to the ones in my code with the correct values to be able to do the operations.

#!/bin/bash  fileCal="$  1"  #file in_calc is entered  d=( ["zero"]="0" ["one"]="1" ["two"]="2" ["three"]"3" ["four"]="4" ["five"]"5" ["six"]="6" ["seven"]="7" ["eight"]="8" ["nine"]="9" ["plus"]="+" ["minus"]="-"  ["times"]="\*" ["div"]="/" ["modulo"]="%")   if [ "$  #" == 0 ]; then     echo $  error elif [ -f $  fileCal ]; then     read -a $  fileCal  fi

How to convert multi-value answers into single column in Google Forms’ response sheet?

I have a Google form that asks for Name and up to 3 Score. The data is dumped into a sheet like this

enter image description here

But that data is not very convenient. I want to have the data like this…

enter image description here

Can I do that by adding a new sheet to the workbook, and some kind of LOOKUP formula? Or can I change the settings on the FORM to write up to 3 rows per submit?

How to convert X,Y Cartesian data to 3D spectrum (frequency, direction, spectral density)?

My question is as follows. I have x,y motion. normally I would ignore directionality and just look at the spectral density of each by performing a FFT on it. For my current problem directionality is crucial. I would like to create a 3D spectrum, frequency, direction and spectral density. I presume I would convert from cartesian to polar coordinates and then convert to frequency domain. Is this the best method and any help on how to do this wold be great. My google skills cant seem to find anything. Thank you
