X908: expandAndCopyArray Write a method that takes an argument representing an array, orig, and returns a new array that is 50% bigger than the original one. The new array should also have all the values copied over to the new array. Examples: expandAndCopyArray ( {1, 10)) -> (1, 10, 0) Your Answer: 1 public static int[] expandAndCopy (int[] array) 2 (

int [] arrayInt={3,54,90,22,32}; To print the last element in the arrayInt you will write:     a. System.out.println(arrayInt[5]);     b. System.out.println(arrayInt[0]);     c. System.out.println(arrayInt[length]);     d. System.out.println(arrayInt[4]);

1) Write a method that returns the range of an array of integers. The range is the difference between the highest and lowest values in the array. The signature of the method should be as follows. public static int computeRange(int[] values)

Write java code that recursively calculates the Sum of the array cells. Program requirements: Create an array named MyArr and initialize it as follow: 19 27 81 243 88 1- Write a method named ArrSum that recursively calculates the Sum of the numbers in the Array and returns the Sum of the numbers. Hint: Method with 1 parameter (the Array) that returns 1 value (the Array's Sum). 2- Write a method named Display that displays the Array contents and Sum of the numbers. Hint: Method with 2 parameters (the Array) and Sum with no returns (void) 3- Your program output format must be the same as the following: =>> Array Summation Array: 31 19 27 81 243 88 100 6 10 5 Sum: 610 =>> End of the Program Documentation / Comments 31 100 6 10 5

How is this program written in java?

In Java Assignment 5B : Maze Game! 2D Arrays can be used to store and represent informationabout video game levels or boards. In this exercise, you will use this knowledge tocreate an interactive game where players attempt to move through a maze. You willstart by creating a pre-defined 2D array with the following values:{"_","X","_","X","X"}{"_","X","_","X","W"}{"_","_","_","X","_"}{"X","X","_","_","_"}{"_","_","_","X","X"}You will then set the player (represented by “O”) at index 0, 0 of the array, the top-leftcorner of the maze. You will use a loop to repeatedly prompt the user to enter adirection (“Left”, “Right”, “Up”, or “Down”). Based on these directions, you will try tomove the player.• If the location is valid (represented by “_”), you will move the player there• If the location is out of bounds (e.g. index 0, -1) or the command is invalid, youwill inform the player and prompt them to enter another direction• If the location is a wall (represented by “X”), you will tell the…
