Why does the foreach statement not change the element value?

Question

How come the following prints boss and not bass?

String boss = \"boss\";
char[] array = boss.toCharArray();

for(char c : array)
{
 if (c== \'o\')
     c =          


        

Answer 1

You variable c gets changed, but not the array contents. To change the array, don't use c, manipulate the array directly.

for(int i = 0; i < array.length; i++)
{
 char c = array[i];
 if (c== 'o')
     array[i] = 'a';
}
