Array initializer is not allowed here [duplicate]

Question

I am working on Android project and I am getting an error which I cannot understand:

Array initializer is not allowed here

I tried to simplify my code and it comes down to this

public class MainActivity extends Activity{      int pos = {0, 1, 2};      @Override     protected void onCreate(Bundle savedInstanceState){         super.onCreate(savedInstanceState);         setContentView(R.layout.main);         pos = {2, 1, 0};     } } 

What is going on here?

Answer 1

You should use

pos = new int[]{1,2,3}; 

You can only use the abbreviated syntax int[] pos = {0,1,2}; at variable initialization time.

private int[] values1 = new int[]{1,2,3,4}; private int[] values2 = {1,2,3,4}; // short form is allowed only at variable initialization 

Answer 2

Your initialization statement is wrong: you must add square brackets to declare an array (and here you can omit the new keyword because you're declaring and initializing the variable at the same time):

int[] pos = { 0, 1, 2 }; 

In the onCreate method, you can't omit the new keyword because the variable was already declared, so you have to write:

pos = new int[] { 2, 1, 0 }; 

You can read the Oracle documentation and the Java Language Specs for more details.
