For practice in writing and using methods that take an array parameter, copy Initializers.java to Initializers2.java and modify it as follows first write two sets of new, overloaded display() and fill() methods ahead of main that take array parameters:

Define two overloaded versions of a static void display() method:

static void display(String header, int[] a) if the header is not the empty String, print it followed by a space, using System.out.print(); in any case, print all the elements of array a, separated by single spaces, across one line, then print a blank line. Hint: copy the second version of the printing for loop from Initializers.

static void display(int[] a) call display("", a); // no header

Define three overloaded versions of a static void fill() method:

static void fill(int[] a, int start, int diff) fill up array a with values starting with start and adding diff for each element

static void fill(int[] a, int start) call fill(a, start, 2); // diff 2

static void fill(int[] a) call fill(a, 2, 2); // start at 2, diff is 2

Now modify main (parts carried over from Initializers are in blue):

Declare and instantiate an int array named array1 having size 10 using the Java array initializer syntax with { } to fill array1 with the even integers 2 through 20, then use the first version of the display() method, defined above, to print out the values of array1, preceded by the String "array1:".

Now ask the user how long to make the array, and assign a new array of that length to reference variable array1, then fill it with even integers starting with 2; use the third version of the fill() method, defined above; finally, print array1 using display() as in #3 above. Using fill() and display() makes main much simpler.

And here is my code below: (I'm not sure if this is right..)

import java.util.Arrays;

public class Initializers

{

public static void main(String[] args)

{

int[] numbers = {12, 193, 56, 74, 9, 34, 165, 102, 154, 63, 19, 49};

System.out.print("UNSORTED Array is ");

for (int array : numbers)

{

System.out.print(array+" ");

}

Arrays.sort(numbers);

System.out.println(" SORTED Array is ");

for (int array : numbers)

{

System.out.print(array+" ");

}

}

}
