You can use the method random.nextInt() to generate a random number for the position. If you want to generate a random character you should use : (char)(random.nextInt(max-min)+min). Where the max and min value are the ascii code of the max and the min char. If you only want to generate a char in some char you should create an array with these character and use yourArray[random.nextInt(yourArray.length-1)+1];

Edit : You have to create the object random at the beginning of your code. Random random = new Random();
