Add three integers and report the sign of the sum
Use shorthand for addition, multiplication, division etc.

E.G instead of this.total = this.total + number;

do: this.total += number;

You have a lot of code repetition with these two methods. Anytime you copy &amp; paste, you should be asking yourself if you can make the code shorter.

With your overloaded method, it's easy. Just change your no-arg constructor to call the other:

public void status(){
    status(this.total);
} 


You may also want to change the name to printStatus. You can further reduce the code, since all of the if statements print a lot of the same characters 

E.G:

public void status(total){
    String status = "The sum is ";

    if(total&lt;0) {
            status += "negative.";
    } else if (total&gt;0) {
            status += "positive";
    } else {
           status += "equal to zero.";
    }

    System.out.println(status);
}
