Solved Stringing ArrayList Together

How would I get all the contents of an ArrayList and add them to each other in a string?

For example, the following code would add strings to an ArrayList:

Code:

ArrayList<String> str = new ArrayList<String>();
 
str.add("i");
str.add("like");
str.add("pie");

Now I want to make it so I can get the string "i like pie" from the ArrayList.

Okay thanks, I know how to do most of this now.

However, how would I do this:

Code:

List<String> str = new ArrayList<String>();
 
str.add("i");
str.add("like");
str.add("pie");
 
str.get(0);
//all the up to:
str.get(str.size());
//but without putting the get methods in a for loop

 

Failplease You would have to do some sort of loop. There is no way to change to code every time the size is changes. Why would you not want to use a loop?

 

Code:java

String msg = "";
for(String s : list){
msg+=s + " ";
}

??

 

StringUtils.join(list, ' ');

If I use a loop, then I will not be able to access the message from outside of the loop.

 

Code:java

for(int i = 0; i<str.length; /*Not sure if this is right, either length or size()*/ i++){
 
stuff = stuff + " " + str.get(i);
 
}

 

Don't use a local variable then.

I'm not that advanced...
How do I not use a local variable?
