Write a Java program tat prompts user for a list of integers with 0 as the last value.Save the values in an array. Assume there can be maximum 100 values. Theprogram should have the following methods:- A method that takes the array as parameter and updates each value in thearray to the square of the value.- Another method that takes the original and modified arrays as parametersand displays the original and the squared values.

Task 2: Write a static method which takes an ArrayList of Strings and an integer and changes the ArrayList destructively to remove all Strings whose length is less than the integer argument. So if the integer argument is 4 and the ArrayList is: tomato cheese chips fruit butter tea buns pie The output tomato cheese chips fruit butter is:
