Question

I have a class in Java which has 2 fields like

Class A
{
  int i;
  double v;
}

I make an array of object of class A like:

A[] x = new A[3];

After assigning the memory to object I assign value to object like:

A[0].i = 1;
A[0].v = 2.5;
A[1].i = 2;
A[1].v = 3.5;
A[2].i = 55;
A[2].v = 1.5;

I was wondering it there was a better way to initialize the object-values.

Answer 1

Yes: use constructors:

A[] x = new A[]{new A(1, 2.5), ... };

Update: wrt. to comment below:

// Fake constructor
public static A new_A(int i, double v) {
    A x = new A();
    x.i = i;
    x.v = v;
    return x;
}

A[] x = new A[]{new_A(1, 2.5), ... };
