Sorting an array.
Knowledge and experience.
here you will a good example on java sorting algorithm application http://javacodespot.blogspot.com/2010/08/java-sorting-animations.html http://javacodespot.blogspot.com/
Internal sorting it means we are arranging the number within the array only which is in computer primary memory. External sorting it is the sorting of numbers from the external file by reading it from secondary memory.
The built in array sorting algorithm (java.util.Arrays.sort) depends on the type of data being sorted. Primitive types are sorted with a modified implementation of quicksort. Objects are sorted with a modified implementation of mergesort.
Object[] arrayToBeSorted; Arrays.sort(arrayToBeSorted);
merge sort is the most efficient way of sorting the list of array.
Java has a very efficient built in implementation of quick sort. You can use it on any array of primitives or Comparable Objects by invoking Arrays.sort(<array>) See related link.
void bubblesort (int* array, int size) { if (!array size<2) return; int last_swap = size; while (last_swap>0) { int n=last_swap; for (int i=1; i<last_swap; ++i) { if (array[i]<array[i-1]) { array[i]^=array[i-1]^=array[i]^=array[i-1]; n=i; } last_swap = n; } }
packing and sorting
If it is already sorted, the best is to leave the array as it is.If it is already sorted, the best is to leave the array as it is.If it is already sorted, the best is to leave the array as it is.If it is already sorted, the best is to leave the array as it is.
