Batch Changing
You have found the correct box to change. Hurray ! Unfortunately, with a forEach loop, you cannot easily change the content. To that end, you slightly change your program and use a for loop. The weight of the new bag is 198.
This exercise is part of the course
Intermediate Java
Exercise instructions
- Write down the correct limit for the iterator.
- Input the correct index to change the list
weights. It should work even if the element's position changes.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
class WeightChanger {
public static void main(String[] args) {
int[] weights = {198, 190, 188, 187, 190, 198, 201, 250, 203, 210, 205, 170, 180, 200, 203, 210, 180};
// Write down the correct limit for the iterator
for (int i = 0; i < ____.____; i++) {
int weight = weights[i];
if (weight > 220) {
// Input the correct index to change the list. It should work even if the element changed location.
weights[____] = 198;
}
}
for (int weight : weights){
System.out.println(weight);
}
}
