Java arraylist int
This section demonstrates the use of for loop for int data type.
This section demonstrates the use of for loop for int data type.
- arraylist can contain int data type elements also.
- Only wrapper class object is allowed to be added.
- But due to boxing unboxing feature primitive datatype gets autoboxed into Wrapper class object.
- In this example int data type gets converted into Integer data type.
Example of Java Arraylist int
import java.util.ArrayList;
import java.util.List;
public class List_for_int {
public static void main(String[] args) {
List list=new ArrayList();
int arr1[]={11,12,13,14,15};
for (int i = 0; i < arr1.length; i++) {
list.add(arr1[i]);
}
for (int i = 0; i < arr1.length; i++) {
System.out.println((i+1)+" : "+list.get(i));
}
}
}
Output
1 : 11
2 : 12
3 : 13
4 : 14
5 : 15
