Write a program, named last10.java, whose input is an unknown number of integers. The program stops reading when it encounters a -1. The program then prints the last ten numbers it read (not including the-1), in the order they were given. If less than 10 numbers were input, the program should print them all. For example, here are two screenshots of my program in action: The below screenshot shows an example where the user enters more 10 number. Input is shown on the first line (green), and the output is shown in black on the second line. 1 2 3 4 5 6 7 8 9 10 11 12 -1 3 4 5 6 7 8 9 10 11 12 Here is another example where the user enters less than 10 numbers. 1 2 3 4 5 6-1 1 2 3 4 5 6 Your program must not assume anything about the number of input values, which means that you can't declare an array to hold all of them. Instead, you should declare an array of 10 integers. In particular, keep a variable to the next open slot of the array. Use a Scanner to read an integer. If it is not -1, write it to that slot and increment the value. If incrementing the value puts it beyond the end of the array, set index of array back to the first slot. When you read a zero, print the contents of the array. Note that you need to begin with the number that was entered least recently, which is not necessarily the number at the beginning of the array. See the first example in the above screenshot. Some people will want to implement the answer like this: Once the array is full, you shift the values in the array one position to the left in order to make room the next input value, which you insert at the far right of the array. This is awkward and inefficient, and a bad idea. Please DON'T do it this way.
