I need help with Java (I’m a beginner in programming). I have a list of registered firebase players and I need to connect each player with their respective race time. A player has an id= player1 and has a time with id= time1 and so on until player8/timeJourer8 and I need to list in order of time and for that I compare the value of each time, but the time and the player of that time have to appear. follows the code I have here:

What about Javascript code? It’s like [Edit] the question and put it?
– Woss
If you need more I command. This is what makes the data tabulation.
– Jadson Alves
You can put what you give here
console.log(snapshot);before the.forEach? So you want to sort that data before you produce HTML?– Sergio
