Java Program Write a menu driven test program that prompts the user to choose which of your methods to test out or to exit. The user is then to enter his/her choice: 1. In the case of string permutation they enter a string and the program displays all its permutations, then returns to the menu. 2. In the case of the hex the user enters a hex string and the program displays its decimal equivalent, then returns to the menu. 3. In the case of the binary the user to enters a binary string and the program displays its decimal equivalent, then returns to the menu. 4. In the case of the decimal the user to enters a decimal number and the program displays its hex equivalent, then returns to the menu. 5. Boundary, recursive programs can quickly get out of hand complexity wise, Prompt the user at the start of your program to set an upper bound on input size, warm them of time delay in case of large inputs (say greater than 6 digits or chars). 6. In the case of exit, display how much time elapsed and the number of recursive cals per function requested (bonus 1 point), then the program is to exit without leaking any resources...
