How to declare array of class types in Java

Question

I have a java code like below.

myclass a1 = new myclass(p1,p2);
myclass a2 = new myclass(p3,p4);

I want to do something like

myclass a[1] = new myclass(p1,p2);
myclass a[2] = new myclass(p3,p4);

how to do it ?

In c#? You are interested in having an array of custom objects, yes? — ModS

myclass[] a = new myclass[2]; and then a[0] = new myclass(p1, p2); a[1] = new myclass(p3, p4);. — Kayaman

myclass[] myArray = new myclass[5];

myArray[0] = new myclass(p1,p3)

This is valid in java.

Try this:

myclass[] a = new myclass[]{
    new myclass(p1,p2),
    new myclass(p1,p2)
};

it could be done in one line:

myclass[] myArray = myclass[]{ new myclass(p1, p2), new myclass(p3, p4) };

This is the same as:

myclass[] myArray = new myclass[2];
myArray[0] = new myclass(p1, p2);
myArray[1] = new myclass(p3, p4);
