The output: result = 1001

Can you explian me the following code?

public class ObjComp {

public static void main(String[] args) {

int result = 0;

ObjComp oc = new ObjComp();

Object o = oc;

if (o == oc) {

result = 1;

}

if (o != oc) {

result = result + 10;

}

if (o.equals(oc)) {

result = result + 100;

}

if (oc.equals(o)) {

result = result + 1000;

}

System.out.println("result = " + result);

}

}
