I have an ArrayList full of small Strings. How can I combine them so I get one big String as a result?

Question

I have an arraylist with 5 cells with type String:
0: AU
1: ~T
2: H~
3: O
4: ~R

I want to combine them to make one string:
"AU~TH~O~R"

As a bonus I'd like to completely remove the tildes (~).

Any help would be appreciated. Thanks

Answer 1

you can concatenate strings with the overloaded "+" operator, so if you iterate through the array(i'm assuming an array list is the same thing as an array) you can put all the strings together. for example:
string tempstring = "";
for(int i = 0; i < 5; i++)
tempstring += arraylist[i];

that will set tempstring equal to "AU~TH~O~R"

to remove the tilde's you can use something like this
int blah = tempstring.find("~");
string tempstring2;
tempstring2 = tempstring.substr(0,blah) + tempstring.substr(blah,tempstring.length);
until tempstring.find("~"); returns string::npos
when that happens "~" does not exist in the string

hope this helps

Answer 2

declare a string variable.
put a for loop that goes 5 times(the length of the array)
concatenate the array variable to the string variable u declared.
thats all.
Ex:(in java)// let the array name be arr[]

String str;
for(int i=0;i { str = str+arr[i]; }

I think this would do. If u do not want the tildes, use ascii values to check the characters...

You know you can use "for" loop or do it manually.
We assume that arrName is the name of your arrayList.
string str="";;
for(int i=0;i {
str=str+arrName[i];
}

Also you can do it manually:
string str;
str=arrName[0]+arrName[1]+arrName[2]+arrName[3]+arrName[4];

In javascript it would be e.g.
var my_array=new Array();
my_array[my_array.length] = 'AU';
my_array[my_array.length] = '~T';
my_array[my_array.length] = 'H~';
my_array[my_array.length] = 'O';
my_array[my_array.length] = '~R';
var string=''; for (var i=0; i string+=my_array[i].replace(/~/,''); }
