Simple Java Programming: Sorting An Array

This is the Java program, MyList, an interactive system which allows users to input the size of an array and the desired elements for the array. The array is then sorted using the java.util package.

It contains the following functions:
- showAscending: using for-loop, it shows the elements in an ascending order
- showDescending: using for-loop, it prints the array in reverse, from last to first
- showMax: it selects the last element in the sorted array
- showMin: it selects the first element in the sorted array
- showPrime: calculates each element in the array using a Boolean expression by selecting an odd number value and divides it within a while-loop. Shows only prime numbers

Flowchart

---START---

public class MyList{

//Main insertion sorting
static void insert(int[] array, int free_pos, int val) {
int pos = 0;
for(; pos < free_pos; ++pos) {
if(array[pos] > val) {
break;
}
}

for(int i = free_pos; i > pos; --i) {
array[i] = array[i - 1];
}

array[pos] = val;
}
//Array command for insertion sort
static void sort(int[] array) {
for(int i = 1; i < array.length; ++i) {
insert(array, i, array[i]);
}
}

//Main Command
public static void main(String args[]){

int x=Integer.parseInt(args[0]);
int[] y;
y = new int[x];

for(int i = 0; i < x.length; ++i) {
int y=Integer.parseInt(args[i]);
}

System.out.println("The ascending is: " +x);

System.out.println("The descending is: ");

System.out.println("The max number is: ");

System.out.println("The min number is: ");

System.out.println("The prime numbers are: ");

}
}
