The get() method of java.util.AbstractList class is used to return the element at the specified position in this list.
Syntax:
Java
Java
public abstract E get(int index)Parameters: This method takes index of the element as a parameter, the element at which is to be returned. Returns Value: This method returns the element at the specified position in this list. Exception: This method throws IndexOutOfBoundsException if the index is out of range (index = size()). Below are the examples to illustrate the get() method. Example 1:
// Java program to demonstrate
// get() method
// for Integer value
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
throws Exception
{
try {
// Creating object of AbstractList<Integer>
AbstractList<Integer>
arrlist1 = new ArrayList<Integer>();
// Populating arrlist1
arrlist1.add(10);
arrlist1.add(20);
arrlist1.add(30);
arrlist1.add(40);
arrlist1.add(50);
// print arrlist1
System.out.println("ArrayListlist : "
+ arrlist1);
// getting the value at the index 3
// using get() method
int value = arrlist1.get(3);
// print the value
System.out.println("Element at index 3 : "
+ value);
}
catch (IndexOutOfBoundsException e) {
System.out.println("Exception thrown : " + e);
}
}
}
Output:
Example 2:
ArrayListlist : [10, 20, 30, 40, 50] Element at index 3 : 40
// Java program to demonstrate
// get() method
// for IndexOutOfBoundsException
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
throws Exception
{
try {
// Creating object of AbstractList<Integer>
AbstractList<Integer>
arrlist1 = new ArrayList<Integer>();
// Populating arrlist1
arrlist1.add(10);
arrlist1.add(20);
arrlist1.add(30);
arrlist1.add(40);
arrlist1.add(50);
// print arrlist1
System.out.println("ArrayListlist : "
+ arrlist1);
// getting the value at the index 7
// using get() method
System.out.println("\nTrying to get "
+ "the element from out"
+ " of range index ");
int value = arrlist1.get(7);
// print the value
System.out.println("Element at index 7 : "
+ value);
}
catch (IndexOutOfBoundsException e) {
System.out.println("Exception thrown : " + e);
}
}
}
Output:
ArrayListlist : [10, 20, 30, 40, 50] Trying to get the element from out of range index Exception thrown : java.lang.IndexOutOfBoundsException: Index: 7, Size: 5
