MyArray[nexti] = MyString; doens't seem to work...
i tried using a list: MyList.add(MyString); not working...

Arrays are always of fixed size, so if you want to add something to an array you can create a new array that is one index larger, copy existing values to that array and then assign the value at the last index.

//assuming myArray is the array you want to add to, toAdd is the string added

String[] temp = new String[myArray.length+1];
for(int i=0;i<myArray.length;i++)temp[i]=myArray[i];
temp[temp.length-1]=toAdd;
myArray=temp;

Alternatively you can use utility methods in classes Arrays and Collections.

ah thanks didn't know about the fixed size

As Londbrok says, if you don't know in advance how many items you'll need to store, or the number of items can vary, use a collection class such as ArrayList.

Awaken people's curiosity. It is enough to open minds, do not overload them. Put there just a spark...
