Java Sort int Array Example
This example shows how to sort an int array using sort method of Arrays class of
java.util package.
*/
import java.util.Arrays;
public class SortIntArrayExample {
public static void main(String[] args) {
//create an int array
int[] i1 = new int[]{3,2,5,4,1};
//print original int array
System.out.print("Original Array :\t ");
for(int index=0; index < i1.length ; index++)
System.out.print(" " + i1[index]);
/*
To sort java int array use Arrays.sort() method of java.util package.
Sort method sorts int array in ascending order and based on quicksort
algorithm.
There are two static sort methods available in java.util.Arrays class
to sort an int array.
*/
//To sort full array use sort(int[] i) method.
Arrays.sort(i1);
//print sorted int array
System.out.print("\nSorted int array :\t ");
for(int index=0; index < i1.length ; index++)
System.out.print(" " + i1[index]);
/*
To sort partial int array use
sort(int[] i, int startIndex, int endIndex) method where startIndex is
inclusive and endIndex is exclusive
*/
int[] i2 = new int[]{5,2,3,1,4};
Arrays.sort(i2,1,4);
//print sorted int array
System.out.print("\nPartially Sorted int array :\t ");
for(int index=0; index < i2.length ; index++)
System.out.print(" " + i2[index]);
}
}
/*
Output Would be
Original Array : 3 2 5 4 1
Sorted int array : 1 2 3 4 5
Partially Sorted int array : 5 1 2 3 4
