The hashCode() method of java.util.AbstractList class is used to return the hash code value for this list.
Syntax:
Java
Java
public int hashCode()Returns Value: This method returns the hash code value for this list. Below are the examples to illustrate the hashCode() method. Example 1:
// Java program to demonstrate
// hashCode() 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 code = arrlist1.hashCode();
// print the value
System.out.println("HashCode : " + code);
}
catch (IndexOutOfBoundsException e) {
System.out.println("Exception thrown : " + e);
}
}
}
Output:
Example 2:
ArrayListlist : [10, 20, 30, 40, 50] HashCode : 38490301
// Java program to demonstrate
// hashCode() method
// for String value
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
throws Exception
{
try {
// Creating object of AbstractList<String>
AbstractList<String>
arrlist1 = new ArrayList<String>();
// Populating arrlist1
arrlist1.add("A");
arrlist1.add("B");
arrlist1.add("C");
arrlist1.add("D");
arrlist1.add("E");
// print arrlist1
System.out.println("ArrayListlist : "
+ arrlist1);
// getting the value at the index 3
// using get() method
int code = arrlist1.hashCode();
// print the value
System.out.println("HashCode : " + code);
}
catch (IndexOutOfBoundsException e) {
System.out.println("Exception thrown : " + e);
}
}
}
Output:
ArrayListlist : [A, B, C, D, E] HashCode : 90690786
