In this task, you are asked to write a program called Swap.java, including at least 3 following methods: Main() swapDigitPairs ( parameter) swapLetterPairs (parameter) In the main method, Use your Panther Number as the input argument, call swapDigitPairs ( parameter) Ask user to input a number and call a method swapDigitPairs to swap the number as shown in the example of the following figure. Ask the user to input a string of letters/numbers and call a method swapLetterPairs to swap the letters as shown in the following example. The method swapDigitPairs accepts an integer n as a parameter and returns a new integer whose value is similar to n’s but with each pair of digits swapped in order. For example, the call of swapDigitPairs(482596) would return 845269. Notice that the 9 and 6 are swapped, as are the 2 and 5, and the 4 and 8. If the number contains an odd number of digits, leave the leftmost digit in its original place. The method swapDigitPairs should not use String class to help the swapping operation. The method swapLetterPairs will conduct similar swapping operation as swapDigitPairs, but accepts a String as a parameter and return the swapped String. You can use String class in this method.

Question

In this task, you are asked to write a program called Swap.java, including at least 3 following methods:

Main()
swapDigitPairs ( parameter)
swapLetterPairs (parameter)

In the main method,

Use your Panther Number as the input argument, call swapDigitPairs ( parameter)
Ask user to input a number and call a method swapDigitPairs to swap the number as shown in the example of the following figure.
Ask the user to input a string of letters/numbers and call a method swapLetterPairs to swap the letters as shown in the following example.

The method swapDigitPairs accepts an integer n as a parameter and returns a new integer whose value is similar to n’s but with each pair of digits swapped in order. For example, the call of swapDigitPairs(482596) would return 845269. Notice that the 9 and 6 are swapped, as are the 2 and 5, and the 4 and 8. If the number contains an odd number of digits, leave the leftmost digit in its original place. The method swapDigitPairs should not use String class to help the swapping operation.

The method swapLetterPairs will conduct similar swapping operation as swapDigitPairs, but accepts a String as a parameter and return the swapped String. You can use String class in this method.
