Assign values to array in another object using setter

Question

protected void Method() {
    ...
    while (st.hasMoreTokens()) {
         int data = Integer.parseInt(st.nextToken());   
         person[a] = new Person();
         person[a].setID(data);
         person[a].setResults(data);
         a++;
    }

}

In another class file

protected void Person() {
    int results[] = new int[5];
     ...
    //getters&setters
    public void setResults(int[] results) {
        this.results = results;
    }
}

The setResults is passing in one value at a time, but the setter is expecting an array, what is a better approach to populate the array in student using setters that only take in one value at a time?

Answer 1

I would recommend using a list for this purpose. But for now, you can use a variable to keep store the index at which the value is inserted in the results array and increment it after each insertion.

protected void Person() {
    int results[] = new int[5];
    int index = 0; // index to insert at
     ...
    //getters&setters
    public void setResults(int result) {
        if(index < 5) {
            this.results[index] = result;
            index++;
        }
    }
}

Then you can call setResults like

int data = Integer.parseInt(st.nextToken());
person[a].setResults(data);
