1). (Finding the smallest element) Write a method that finds the smallest element in an array of integers. Use {1, 2, 4, 5, 10, 100, 2, –22} to test the method.

2). (Increasing array size) Once an array is created, its size is fixed. Occasionally, you need to add more values to an array, but it is full. In such cases, you can create a new, larger array to replace the existing array. Write a method with the following header: public static int[] doubleCapacity(int[] list). The method returns a new array that doubles the size of the parameter list.
