What am I doing wrong here?

I've become somewhat familiar with the code, but when I introduce arrays, it falls apart. class Primary{ abstract class Job { int[ ] stats; String name; } class Tank extends Job { Tank Paladin = new Tank() { int[ ] stats = {4, 9, 10, 4, 4, 5, 4, 7, 1, 3}; String name = ("Pld"); } } public static void main(String[ ]args){ System.out.println(stats[2]); } }

Well you're missing out the semi-colon in your constructor String name = ("Pld"); }; //It should be here You forgot to put the main method inside the Tank class, you're trying to call a non-static variable (stats) inside a static scope (main), lastly the NPP exception because the compiler cannot see any initialization for the array stats. Since arrays are OBJECTS. Try this code: abstract class Job { static int[] stats={4, 9, 10, 4, 4, 5, 4, 7, 1, 3}; String name; } public class Tank extends Job { public String Tank() { String name = ("Pld"); return name; } public static void main(String[ ]args){ Tank Paladin=new Tank(); System.out.println(stats[2]); } }

That works, thank you. But if I want several different jobs, like paladin, wizard and cleric, each with different 'stats', how do i achieve this? paladin.stats [] doesnt seem to work. I want an undefined int [] stats; declared in job, and then assign the stats, or array values, later depending on paladin or wizard or whatever. I feel like there is an easier way than just stats [0] = 3; stats [1] = 6; and so on...

public class Job { int str; int[ ] stats = new int[2]; void motto() { System.out.println("I stand ready!"); } } class MyClass { public static void main(String[ ] args) { Job paladin = new Job(); paladin.str = 4; paladin.stats[0] = 4; paladin.stats[1] = 9; Job gladiator = new Job(); gladiator.str = 10; System.out.println(paladin.stats[1]); } } With this code, it works. But shouldn't I be able to assign values to the array as a whole, rather than paladin.stats[0] = 4; i should be able to do paladin.stats [] = {4,10}

basically i want to assign values to an array, not a value to an array index
