return "[]";
} else {
String result = "[" + elementData[0];
for (int i = 1; i < size; i++) {
result += ", " + elementData[i];
}
result += "]";
return result;
}
}
Here is the complete class:
1 public class ArrayIntList {
2 private int [] elementData;
3 private int size;
4
5 public ArrayIntList() {
6 elementData = new int[100];
7 size = 0;
8 }
9
10 public void add( int value) {
11 elementData[size] = value;
12 size++;
13 }
14
15 public String toString() {
16 if (size == 0) {
17 return "[]";
18 } else {
19 String result = "[" + elementData[0];
20 for ( int i = 1; i < size; i++) {
21 result += ", " + elementData[i];
22 }
23 result + = "]";
24 return result;
25 }
26 }
27 }
This version of the class correctly executes the sample client program, producing
the correct output.
