Метод сизе() враћа број елемената на овој листи.

Пример 1

 import java.util.LinkedList; import java.util.List; public class JavaListSizeExample1 { public static void main(String[] args) { List list= new LinkedList(); list.add(34); list.add(56); list.add(12); list.add(43); System.out.println('List : '+list); //it will return the total size of the list int size= list.size(); System.out.println('Total element of the list : '+size); } } 

Излаз:

 List : [34, 56, 12, 43] Total element of the list : 4 

Пример 2

 import java.util.LinkedList; import java.util.List; import java.util.ListIterator; class Student{ String name; String school; Student(String name, String school){ this.name=name; this.school=school; } public String toString() { return ' Name : '+this.name+' School : '+this.school; } } public class JavaListSizeExample2 { public static void main(String[] args) { List list = new LinkedList(); Student s1= new Student('Reema','Gita Convent School'); Student s2= new Student('Geetu','Gita Convent School'); Student s3= new Student('Saloni','Eicher School'); list.add(s1); list.add(s2); list.add(s3); //returns the total number of students in the list System.out.println('Total students : '+list.size()); for (Student val : list){ System.out.println(val); } } } 

Излаз:

 Total students : 3 Name : Reema School : Gita Convent School Name : Geetu School : Gita Convent School Name : Saloni School : Eicher School
