increasing the element without any replacement in java program

To increase the elements of an array or a list in Java without replacing them, you can use a loop to iterate through the array or list and add a value to each element.

For example, if you have an array of integers and you want to increase each element by 1, you can use the following code:

int[] numbers = {1, 2, 3, 4, 5};

for (int i = 0; i < numbers.length; i++) {
    numbers[i] += 1;
}

System.out.println(Arrays.toString(numbers));  // Output: [2, 3, 4, 5, 6]

This will iterate through the numbers array, adding 1 to each element, and then print the modified array to the console.

If you are using a List instead of an array, you can use the set() method to update the elements in the list:

List<Integer> numbers = new ArrayList<>(Arrays.asList(1, 2, 3, 4, 5));

for (int i = 0; i < numbers.size(); i++) {
    numbers.set(i, numbers.get(i) + 1);
}

System.out.println(numbers);  // Output: [2, 3, 4, 5, 6]

This will iterate through the numbers list, adding 1 to each element, and then print the modified list to the console.
