Question

If a method’s return type is int and if it return’s -1 what does it actually mean?

public int handle_get_multi_leg_net_quote(Message mmsg) throws Exception {          
        if (null != t) {
                     return 1;
        }
        return -1;
    }

Answer 1

It appears to be a code written in another language, maybe it was supposed to be a boolean or even another type of data. One thing you could do is understand what it does in the other language before adapt it to Java.
