What's wrong with my code?

Question

public class Demo {
public final static int MAX = 7;
public static intArray = MAX (4, 6, 3, 2, 1, 9, 7);
public static void printline(int count) {
for(int i = 0; i < count - 1; i++) {
System.out.print("=");
}
System.out.println("=");
}
public static void display() {
System.out.print("[");
for(int i = 0; i < MAX; i++) {
System.out.print(intArray.get(i) + " ");
}
System.out.println("]");
}
public static void selectionSort() {
int indexMin;
for(int i = 0; i < MAX - 1; i++) {
indexMin = i;
for(int j = i + 1; j < MAX; j++) {
if(intArray.get(j) < intArray.get(indexMin))
{
indexMin = j;
}
}
if(indexMin != i) {
System.out.println("Items swapped: [ " + intArray.get(i) + ", " + intArray.get(indexMin) + " ]");
int temp = intArray.get(indexMin);
intArray.set(indexMin, intArray.get(i));
intArray.set(i, temp);
}
System.out.print("Iteration " + (i + 1));
display();
}
}

Answer 1

public static void main(String[] args) {
System.out.print("Input Array: ");
display();
printline(50);
selectionSort();
System.out.print("Output Array: ");
display();
printline(50);
}
}
