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're assigning 'a' to the local variable c, but not to the array element. To make it print bass, you'd need

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