Java List get() Method

The get() method of List interface returns the element at the specified position in this list.

Syntax

Parameters

The parameter 'index' represents the index of the elements to return.

Return

The get() method returns the element at the specified position in this list.

Throws:

IndexOutOfBoundsException- If the index is out of range i.e. index<0 or index>=size().

Example 1

import java.util.LinkedList;
import java.util.List;
public class JavaListGetExample1 {
public static void main(String[] args) {
        List<Integer> list= new LinkedList<>();
for (int i=0;i<6;i++){
list.add(i);
// returns the element at the specified position in this list
int index =list.get(i);
System.out.println("Element "+i+" stored at Index : "+index);
        }
    }
}

Test it Now

Output:

Element 0 stored at Index : 0
Element 1 stored at Index : 1
Element 2 stored at Index : 2
Element 3 stored at Index : 3
Element 4 stored at Index : 4
Element 5 stored at Index : 5

Example 2

import java.util.LinkedList;
import java.util.List;
class Information {
    String idNo, name;
int age;
public Information(String idNo, String name, int age) {
this.idNo= idNo;
this.name = name;
this.age= age;
    }
public String toString(){
return "ID : "+idNo+"\nName : "+name+"\nAge : "+age;
    }
}
public class JavaListGetExample2 {
static int i = 1;
public static void main(String[] args) {
        List<Information> list = new LinkedList<>();
        Information val1 = new Information("15", "Reema panda", 21);
        Information val2 = new Information("16", "Geetanjali Sharma", 21);
        Information val3 = new Information("17", "Ajeet Kumar", 36);
list.add(val1);
list.add(val2);
list.add(val3);
//will get the value at index 2
Information index=list.get(2);
System.out.println(index);
    }
}

Test it Now

Output:

ID : 17
Name :Ajeet Kumar 
Age : 36

Example 3

import java.util.LinkedList;
import java.util.List;
public class JavaListGetExample3 {
public static void main(String[] args) {
        List<Integer> list= new LinkedList<>();
list.add(5);
list.add(56);
list.add(509);
// throws an exception if the index is out of range i.e. index<0  or  index>=size()
int index =list.get(-1);
System.out.println("Element "+-1+" stored at Index : "+index);
    }
}

Test it Now

Output:
