In STS, create one Java project for the homework with a separate package for each question, and use comments liberally in your code: Perform a bubble sort on the following integer array: 1, 0, 5, 6, 3, 2, 3, 7, 9, 8, 4 Write a program to display the first 25 Fibonacci numbers beginning at 0. Reverse a string without using a temporary variable. Do NOT use reverse() in the StringBuffer or the StringBuilder APls. Write a program to compute N factorial. Write a substring method that accepts a string str and an integer idx and returns the substring contained between 0 and idx-1 inclusive. Do NOT use any of the existing substring methods in the String, StringBuilder, or StringBuffer APls. Write a program to determine if an integer is even without using the modulus operator (%) Sort two employees based on their name, department, and age using the Comparator interface
