java code for bubble sort code example

Example: bubble sort in java

{
	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; 
            }
        }
    }
