Sorting Array Elements

To sort an array follow the steps given below.

• Compare the first two elements of the array

• If the first element is greater than the second swap them.

• Then, compare 2^nd and 3^rd elements if the second element is greater than the 3^rd swap them.

• Repeat this till the end of the array.

Swapping an array

• Create a variable (temp), initialize it with 0.

• Assign 1^st number to temp.

• Assign 2^nd number to 1st number.

• Assign temp to second number.

Example

import java.util.Arrays;
public class SortingArray {
   public static void main(String args[]) {
   
     // String[] myArray = {"JavaFX", "HBase", "OpenCV", "Java", "Hadoop", "Neo4j"};
      int[] myArray = {2014, 2545, 4236, 6521, 1254, 2455, 5756, 66406}; 

      int size = myArray.length;
      for(int i = 0; i<size-1; i++) {
         for (int j = i+1; j<size; j++) {
            if(myArray[i]>(myArray[j])) {            
               int temp = myArray[i];
               myArray[i] = myArray[j];
               myArray[j] = temp;
            } 
         }     
      }
      System.out.println("Sorted array :"+Arrays.toString(myArray));     
   }
}

Output

Sorted array :[1254, 2014, 2455, 2545, 4236, 5756, 6521, 66406]
