Question
Add the following method to the ArrayIntList class from this chapter.
Write a method called replaceAll that accepts two integer values as parameters and replaces all occurrences of the first value in the list with the second value. For example, if a variable called list stores [11, –7, 3, 42, 3, 0, 14, 3] , the call of list.replaceAll(3, 999); should change the list to store [11, –7, 999, 42, 999, 0, 14, 999] .
Answer
Implementation of replaceAll method:
public void replaceAll(int oldValue, int newValue)
{
for(int i = 0; i < size; i++)
{
if(elementData[i] == oldValue)
{
elementData[i] = newValue;
}
}
}
