sort array java
Here’s the java program to sort an array using Arrays.sort() method.
import java.util.Arrays;
public class JavaArraySortMethod
{
public static void main(String[] args)
{
String[] strGiven = {"Great Barrier Reef", "Paris", "borabora", "Florence","tokyo", "Cusco"};
Arrays.sort(strGiven);
System.out.println("Output(case sensitive) : " + Arrays.toString(strGiven));
}
}Arrays.sort() in java
// how to sort an array in java without using sort() method (ascending order)
public class WithoutSortMethod
{
public static void main(String[] args)
{
int temp;
int[] arrNumbers = {14, 8, 5, 54, 41, 10, 1, 500};
System.out.println("Before sort: ");
for(int num : arrNumbers)
{
System.out.println(num);
}
for(int a = 0; a < arrNumbers.length; a++)
{
for(int b = a + 1; b < arrNumbers.length; b++)
{
if(arrNumbers[a] > arrNumbers[b])
{
temp = arrNumbers[a];
arrNumbers[a] = arrNumbers[b];
arrNumbers[b] = temp;
}
}
}
System.out.println("---------------");
System.out.println("After sort: ");
for(int num : arrNumbers)
{
System.out.println(num);
}
}

int[] arr = { 13, 7, 6, 45, 21, 9, 101, 102 };
Arrays.sort(arr);//sort() function
