Question

I am very new to Java, so this could seem too easy for most people….Is this completely wrong?
My question is how to write a method selectRandom(String[] names),
which returns a randomly selected name from the given array.

Each name should be selected with equal probability.

public static String selectRandom(String[] names)    
{    
    String num = names[0]; 
    int[]newArray = new int[names.length];
    for(int i =0; i<names.length;i++)
    {
      Random r = new Random();
      int ranNum= r.nextInt(names.length)+1;
      num = names[ranNum];
    }
    return num;  
}

Answer 1

public static String selectRandom(String[] names)    
{    
      Random r = new Random();
      int ranNum= r.nextInt(names.length);
      return names[ranNum];

}

You don’t need most of the codes inside your method. Maybe you should try something like this?
