Program 1: Sort the Elements of an Array in Descending Order In this approach, we will see how to use loops to sort an array in descending order. We can sort the array using manual sorting like using for loops. What we can do is use two for loops, one to traverse the array from t...

The program output: [Task[id=5,name=Five,status=true],Task[id=1,name=One,status=true],Task[id=3,name=Three,status=true]] 5. Conclusion In conclusion, we can say that sorting an arraylist is simple and easy in most cases. For specific cases, it is good to know the requirements and...

Step 3: Repeat the process: After completing one pass through the entire list, the largest element will have "bubbled" to its correct position at the end of the list (in case of ascending order). The algorithm then repeats for the remaining elements, ignoring the last element as it is ...

Before implementing Java program for bubble sort let's first see how bubble sort functions to sort array elements in either ascending or descending order. Bubble sort is the simplest sorting algorithm among available ones. However, its simplicity does not carry much value because it is one of ...
