help in java![1) The first variable, x, will be used to create an integer array of size x, which should be filled starting with the value of x n the last index. Use a method createxArray(int x) that returns the newly created array. For and descending to 1 example, ifx is 20, it should create an array of length 20 with the first index containing 20 and the last index containing 20 1. 9 18 1 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 Instructor note: Did you ask yourself: What happens if x is less than 1 This would be an error condition you as the program should handle mer To resolve this, you will explicitly throw and out of bounds error. In other words, detect the error condition, but dont print a message about bad data or make any adjustments, just force an exception that is passed back to the calling program. In our case, the calling program is not going to handle it, so the default exception handler will kick in. Youll see! An example is at the end of these instructions What will you use to verify the array i correctly initialized? The debugger? A print method Such questions go in the side note. 2) The second variable, y, will be used to call a method createYArray(int y int [1 xArray) to create a second integer array of size y which should be filled with random numbers taken from the xarray. It is okay to have repeating values in your second array. This this example, x was 20 and y is 10 18 10 4 11 5 3 6 3 15 7 You should import the java.util. class, and give it the seed 123L (the L is for long integer value) when choosing the index to take fr om your rray and put it into your y-array Instructor note: Say what? That sentence doesnt even make sense! Must ask for clarification from the instructor. And here it is: That should read You should import the java .util.Random class, and initialize it with a seed value: Random rand new Random (123L) Use ran to get an x-array index at random, such that y-array [i] randomIndex] may be repeated until the y-array is entirely initialized array How will you handle bad input? Again, throw an ArraylndexOutofBoundsException 3) Create a method ray (int array) where a oop prints out a one-dimensional array on one line with one space in between each number and ends with a newline. [Instructor note: Ah hah! This answers the how to verify the array question earlier 4) Create a method getIdentificationstring that returns your identification string. Think about code re-use method you can go get and modi In this program, the did you already write a get. Identificationstring method will return RandomArray, Your FirstName YourLastName As in the first program, this program will not call this method but it will be tested with a unit test. 5) Create a method main that reads in an xand a y value, creates x-array, prints it, creates the y-array, prints it Ex. Ifx 20 and y-10 then the output numbers should be this exactly 20 6 15 3 22 20 9 8 7 6 5 4 3 2 1](https://d2vlcm61l7u1fs.cloudfront.net/media%2F00e%2F00e173f0-216f-49ac-855a-016b5a8973ca%2Fphpojsp0V.png)
The first variable, x, will be used to create an integer array of size x, which should be filled starting with the value of x and descending to 1 in the last index. Use a method createXArray (int x) that returns the newly created array. For example, if x is 20, it should create an array of length 20 with the first index containing 20 and the last index containing 1. [Instructor note:Did you ask yourself: What happens if x is less than 1? This would be an error condition you as the program should handle. To resolve this, you will explicitly throw and out of bounds error. In other words, detect the error condition, but don’t print a message about bad data, or make any adjustments:just force an exception that is passed back to the calling program. In our case, the calling program is not going to handle it, so the default exception handler will kick in. You’ll see! An example is at the end of these instructions. What will you use to verify the array is correctly initialized? The debugger? A print method?” Such questions go in the side note.] The second variable, y, will be used to call a method createYArray (int y, int [] xArray) to create a second integer array of size y, which should be filled with random numbers taken from the x-array. It is okay to have repeating values in your second array. This this example, x was 20 and y is 10: You should import the java. util. Random class, and give it the seed 123L (the L is for long integer value) when choosing the index to take from your x-array and put it into your y-array. And here it is:That should read: You should import the java .util. Random class, and initialize it with a seed value:Random rand = new Random (123L);. Use rand. nextInt () to get an x-array index at random, such that y-array [i] = x-array [randomIndex] may be repeated until the y-array is entirely initialized. How will you handle bad input? Again, throw an ArraylndexOutofBoundsException. Create a method printArray (int [] array) where a loop prints out a one-dimensional array on one line with one space in between each number and ends with a newline. Create a method getIdentificationstring () that returns your identification string. Think about code re-use:did you already write a getIdentificationstring () method you can go get and modify? In this program, the method will return: As in the first program, this program will not call this method but it will be tested with a unit test. Create a method main (.. .) that reads in an x and a y value, creates x-array, prints it, creates the y-array, prints it. Ex. If x = 20 and y = 10 then the output numbers should be this exactly:
