bubble sort array java code example

Example 1: bubble sort in java

public static void bubbleSort(int arr[])
{
	for (int i = 0; i < arr.length; i++) //number of passes
    {
		//keeps track of positions per pass      
    	for (int j = 0; j < (arr.length - 1 - i); j++) //Think you can add a -i to remove uneeded comparisons 
        {
          	//if left value is great than right value 
        	if (arr[j] > arr[j + 1])
            {
              	//swap values
            	int temp = arr[j];
              	arr[j] = arr[j + 1];
              	arr[j + 1] = temp; 
            }
        }
    }
}

Example 2: bubble sort java

public class DemoBubbleSort
{
   void bubbleSort(int[] arrNum)
   {
      int num = arrNum.length;
      for(int a = 0; a < num - 1; a++)
      {
         for(int b = 0; b < num - a - 1; b++)
         {
            if(arrNum[b] > arrNum[b + 1])
            {
               int temp = arrNum[b];
               arrNum[b] = arrNum[b + 1];
               arrNum[b + 1] = temp;
            }
         }
      }
   }
   void printingArray(int[] arrNum)
   {
      int number = arrNum.length;
      for(int a = 0; a < number; ++a)
      {
         System.out.print(arrNum[a] + " ");
         System.out.println();
      }
   }
   public static void main(String[] args)
   {
      DemoBubbleSort bs = new DemoBubbleSort();
      int[] arrSort = {65, 35, 25, 15, 23, 14, 95};
      bs.bubbleSort(arrSort);
      System.out.println("After sorting array: ");
      bs.printingArray(arrSort);
   }
}
