List<Object> list = new ArrayList<Object>();
List<Object> l = new ArrayList<Object>();
for (int i = 0; i < list.size(); i++) {
Object[] row = (Object[]) list.get(i);
l.add(Arrays.toString(row));
System.out.println("Element " + i + l);
}
According the that code, output is like that
[Air Bükreş, BU, BUR, [email protected], Doküman Paylaşımı, E-posta]
But I need like that seperately
Air Bükreş
BU
BUR
Doküman Paylaşımı
E-posta
I want it without '[' and ']'
You can define a simple method instead of Arrays.toString(row), that prints out/returns your way
for Object[]
public String printRow(Object[] row) {
StringBuilder s = new StringBuilder();
for (Object object : row) {
System.out.println(object);
s.append(object + "\n");
}
return s.toString();
}
You're question is very unclear, but I believe you are adding an entire array inside a single position of your ArrayList. You probably have list.add(items) somewhere, where items is an Object[] and this will not give any errors as that is also an Object and thus will fit as an item in your list. If you want to add them separately you could use list.addAll(Arrays.asList(items))
It's not at all clear to me what you are trying to achieve in your code. However if you question is "how do I print out a list of strings each on a new line" then here are two answers:
list.stream().forEach(System.out::println);
and
System.out.println(list.stream().collect(Collectors.joining("\n")));
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
public class testo {
public static void main(String args[]){
List<Object> list = new ArrayList<Object>();
list.add("1");
list.add("2");
list.add("3");
list.add("4");
list.add("5");
Iterator<Object> it = list.iterator();
while(it.hasNext()){
System.out.println(it.next());
}
}
}
output:
1
2
3
4
5
Arrays.toString(). It will comma separate the array and add the [] characters.List<Object>orList<Object[]>?Object[]can be aObjectrowyour way.could bedeclared as such for more readability.
