publicintsize() Program to find length of ArrayList using size() In this program, we are demonstrating the use ofsize()method. As you can see, when arraylist is created, the size of it is zero. After adding few elements to the arraylist, the size of arraylist changed to 5 as we have...
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.

It is programmers need to choose or select or get or find a random element or number or string and a random index of an Array or ArrayList in Java. Let us explore Math.random() method with examples. The same code can be used to implement a Lottery Draw t
for (int i = 0; i < numbers.length; i++){ numbers[i] = numbers[i] + i; } As you can see, our new code is much smaller and will remain that way even when we add more elements to the array. There is another way we could write for loops, and that is with the enhanced loo...
