Implement the following reverseArrav() method on integer arrays: public static int I reverseArray (int | A); The method reverseArrav() returns a new array that has same length as a and all the elements of A in reverse order. For example, suppose that A is the following array: 173,42, 11, 14 ,then after executing the method it gives the following array elements : 14 ,11 ,42 ,-3 ,17 2. Write a function using Java and Design a JSwing panel to display the net amount depending on the option selection by the user (Savings/Current) assuming that the textbox, buttons, check box and labels are already defined. If user selected Savings display net amount3Damount *2 If user selected Current display net amount3Damount *5 3. Write a function using Java and Design a JSwing panel to accept a temperature in Fahrenheit and convert it into Celsius assuming that the textbox buttons and labels are already defined. (Celsius= (Fahrenheit +32) * 5 / 18)
