[FIXED] How would you display all the items in an array list in one single line

Issue

How would you go about showing all the elements in an array list in one single line without having to show them on multiple lines. You would use a for loop to show each elememnt on each line but that is not what i am after.

Example ArrayList

ArrayList = {"Apple", "Banana", "Grape"}

Desired Output

"Apple Banana Grape"

NOT DESIRED OUTPUT

"Apple"
"Banana"
"Grape"

Solution

System.out.println(list.stream().collect(Collectors.joining(" ")));
