Answer 1

Answer:

Sorting in Java

There are two in-built methods to sort in Java.

Arrays.Sort() works for arrays which can be of primitive data type also.

// A sample Java program to demonstrate working of

// Arrays.sort().

// It by default sorts in ascending order.

import java.util.Arrays;

public class GFG {

public static void main(String[] args)

{

int[] arr = { 13, 7, 6, 45, 21, 9, 101, 102 };

Arrays.sort(arr);

System.out.printf("Modified arr[] : %s",

Arrays.toString(arr));

}

}

Output:

Modified arr[] : [6, 7, 9, 13, 21, 45, 101, 102]

Collections.sort() works for objects Collections like ArrayList and LinkedList.

// Java program to demonstrate working of Collections.sort()

import java.util.*;

public class GFG {

public static void main(String[] args)

{

// Create a list of strings

ArrayList<String> al = new ArrayList<String>();

al.add("Geeks For Geeks");

al.add("Friends");

al.add("Dear");

al.add("Is");

al.add("Superb");

/* Collections.sort method is sorting the

elements of ArrayList in ascending order. */

Collections.sort(al);

// Let us print the sorted list

System.out.println("List after the use of"

+ " Collection.sort() :\n" + al);

Definition: Sorting means to put data in order; either numerically or alphabetically. There are many times when it is necessary to put an array in order from highest to lowest (descending) or vice versa (ascending).Types of Sorting Algorithms:

Bubble Sort. Merge Sort. Insertion Sort.
