Libgdx - How to get a specific item from an array?

Question

I have a Player class which has

int number;

In main, I store them in Array.

Array<Player> players;

How can I get a player which has for example number=2?

Answer 1

This question is programming in general, and has several ways to do what you say, I recommend you look for OOP.

a solution, general, would encapsulate the variable, "creating getter and setter, you need, eg:

this a simple class;

private int number;

public Player(int num){
   this.number = num;
}

public int getNumber (){
   return number;
}

public void setNumber (int n){
   this.number = n;
}

. In your code for search you can use the solution, using a for, or an iterator

for (int a = 0; a < players.size(); a++){

    int tmpNumber = players.get(a).getNumber();

    if(tmpNumber == 2){
      players.get(a); //the object array with index equal to 
                      //the value of 'a', have, number 2 stored 
                      //in the variable 'number'
    }
}

but this question I think is a little matter of taste or needs you have
