Initialize a static final field in the constructor

Question

public class A 
{    
    private static final int x;

    public A() 
    {
        x = 5;
    }
}

• final means the variable can

Answer 1

static means that the variable is unique on the application. final means that it should be set only once.

If you set it in your constructor, you allow to set the variable more than once.

Hence you should intialize it directly or propose a static method to initialize it.
