The java.util.Arrays.sort(int[]) method sorts the specified array of ints into ascending numerical order.
Following is the declaration for java.util.Arrays.sort() method
public static void sort(int[] a)
a − This is the array to be sorted.
This method does not return any value.
NA
The following example shows the usage of java.util.Arrays.sort() method.
package com.tutorialspoint; import java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { // initializing unsorted int array int iArr[] = {2, 1, 9, 6, 4}; // let us print all the elements available in list for (int number : iArr) { System.out.println("Number = " + number); } // sorting array Arrays.sort(iArr); // let us print all the elements available in list System.out.println("The sorted int array is:"); for (int number : iArr) { System.out.println("Number = " + number); } } }
Let us compile and run the above program, this will produce the following result −
Number = 2 Number = 1 Number = 9 Number = 6 Number = 4 The sorted int array is: Number = 1 Number = 2 Number = 4 Number = 6 Number = 9
