Real World Example You work at a car dealership and your boss asks you to get the color of a car. He tells you the parking lot to get it from (the object you're searching) and then writes exactly where it is. row1 [0].color, he could also give you this direction as an array ["row1", "[0]", "color"]. If there is no color he tells you to tell him "no color found" (the default value). You follow his instructions and return "red". Examples = { "a": [{ "b": { "c": 3 } }] } var object get (object, "a[0].b.c") <-3 get (object, ["a", "0", "b", "c"]) - 3 get (object, "a.b.c", "default") "default"

X42: frontPiece Given an int array of any length, return a new array of its first 2 elements. If the array is smaller than length 2, use whatever elements are present. Examples: frontPiece ({1, 2, 3}) -> {1, 2} frontPiece ({1, 2}) -> {1, 2} Your Answer: Feedback Your feedback will appear here when you check 1 public int[] frontPiece(int[] nums) 2 { your answer. 3 4 }

1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…

Does a method that accepts an array as an argument really have access to the original array, or is it just a copy of it?
