Answer 1

Using the power of java 8 you can do a join :

List<String> myist = Arrays.asList("AROl", "JACOB", "JOSEPH");
String result = String.join("\n", myist);

System.out.println(result);

the result will be

AROl
JACOB
JOSEPH

Answer 2

Try this.

List<String> list = Arrays.asList("AROL", "JACOB","JOSEPH");
String result = list.stream().collect(Collectors.joining("\n ", "[ ", "\n]"));
System.out.println(result);

result:

[ AROL
 JACOB
 JOSEPH
]
