How do change one position in an array when the index is unknown?

I have an array of Strings, and when I initialized the array, i made all the entries "".

later, I need to find the first position in the array where the entry is " and change it to my variable tag. The problem is, whenever I run my code, it changes all the entries to tag.

String[] list = new String[100];

for(int i = 0; i < list.length; i++){
    list[i] = "";
}
//Other method
for(int i = 0; i < list.length; i++){

    if(list[i].equals("")){
        list[i] = tag;
    }
}

This is part of a homework assignment, so I can't use any predefined java API structures or import most things.

You have to break from the loop after the first change to avoid changing all the entries to tag:

//Other method
for(int i = 0; i < list.length; i++){

    if(list[i].equals("")){
        list[i] = tag;
        break;
    }
}
