class Money{
    private int cents;
    private int dollars;
    public Money(){
        this.cents=0;
    }
    public Money(Scanner sc){
        String token=sc.next();
        int dot=token.indexOf(".");
        this.cents=Integer.parseInt(token.substring(dot 1));
        this.dollars=Integer.parseInt(token.substring(1,dot));
    }
    public String toString(){
        return "$" dollars "." cents;
    }
    public boolean equals(Money other){
        if(!(other instanceof Money)){
            return false;
        }
        return this.dollars==other.dollars && this.cents==other.cents;
    }
    public Money add(Money other){
        return 
    }
}

Here is my class, I can't seem to figure out how to create the add method that adds an object's value to the receiver's. Any tips or help is greatly appreciated!

Possible solution assuming that the cents value should always be kept within [0, 100] range in any instance of Money:

public Money add(Money other) {
    if (null != other) {
        this.cents  = other.cents;
        if (this.cents >= 100) {
            this.cents %= 100;
            this.dollars  ;
        }
        this.dollars  = other.dollars;
    }
    return this;
}
