Explanation / Answer

The program in given question requires knowledge of creating our own methods to sort the numbers in the array.

Now, sorting numbers in java is easy because the Arrays class allow us to do everything with us. Arrays is part of java,util group of classes, but we will create our own method here.

method() in java is equivalent to functions in C++, and is essentially a group of statements written together to perform a specific task.

So, let us call our method Sorter.

step 1: Create a method

As you might be familiar with, public static is a modifier, int is the datatype of method, and Sorter is the name of method. a, b,c are the arguments that the method will deal with.

Now comes our code-

public static int Sorter(int a, int b, int c)
{

int a = Integer.parseInt(int);
int b = Integer.parseInt(int);
int c = Integer.parseInt(int);

if ((a > b && a > c))
{
if(b > c)
{
ArrayFill(a,b,c);
//arrayfill is another method we have used to fill numbers in the array.
}
else
ArrayFill(b,c,a);
}
else if ((b > a && b > c))
{
if(a > c)
{
ArrayFill(c,b,a);
}
else
{
ArrayFill(a,c,b);
}
}
else if ((c > a && c > b))
{
if(a > b)
{
ArrayFill(b,a,c);
}
else
ArrayFill(a,b,c);
}
else
{
System.out.println("ERROR!");
}

}

public static int ArrayFill(int, int, int){
int num=0;
int array[] = new int [2];
for ( array[a]=1; array[a]<=array.length; array[a]++){
System.out.println(array[a]);
}

Now, you will need two classes to build your project.

1. Main() class, where you will prompt the user to input three numbers, and display the output.

2. Sorter class (saved as sorter.java and containing the above code for Sorter() and ArrayFill()).
