As you can see here, size of ArrayList was 4, then we removed two elements from it and size of ArrayList became two. That’s how you can find length/size of ArrayList in java.
How can i know the size of array when it is passed to a function. For Example i have this code: #include <stdio.h> #include <stdlib.h> void foo(int * array); int main(void) { int n=5; int array[n]; foo(array); } void foo(int * array) { /*Here how can i know the ...
When we try to add an object to the arraylist, Java checks to ensure that there is enough capacity in the existing array to hold the new object. If not, a new array of a greater size is created, the old array is copied to new array using Arrays.copyOf and the new array is assig...
When the user selects "5" from the menu, the program will sort these tasks by their date. I need to sort all tasks based on the ascending order of the task’s date and time, i.e., the tasks with earlier date and time will be listed before the tasks with later date and time,...

and there's added risk of causing crashes or leaking memory when improperly used. It's also possible in some scenarios to use unsafe code to read and write byte arrays, casting them to and from the appropriate C# data structures. On our team, however, we try very hard not to use unsafe...
