Java Code to write method that returns both max and min number from an array of integers

class Demo{
static int[] getMaxMin(int[] arr){
int max = arr[0], min = arr[0];
for(int i = 0 ; i< arr.length; i++){
if(arr[i]>max){
max = arr[i];
}
if(arr[i]<min){
min = arr[i];
}
}
int[] ans = new int[2];
ans[0] = max;
ans[1] = min;
return ans;
}
public static void main(String[] args){
int[] arr = new int[]{1,2,3,6,4,3,9,7,0};
int[] ans  = Demo.getMaxMin(arr);
System.out.println("Max is: "+ ans[0]+" Min is: "+ ans[1]);
}

}
