Java Given an integer array, determine whether the array is ordered (increasing)

Given an array of integers, determine whether the array is ordered (increasing)

public class Test39 {
    public static void main(String[] args) {
        int[] arr={1,2,3,4,5,6};
        int[] arr2={1,3,2,4,5,6};
        isOrd(arr);
        isOrd(arr2);
    }

    private static void isOrd(int[] arr) {
        boolean ret=false;
        for (int i = 0; i < arr.length-1; i++) {
            if(arr[i]>arr[i+1]){
                ret=true;
            }
        }
        if(ret==false){
            System.out.println("此数组有序");
        }else{
            System.out.println("此数组无序");
        }
    }
}
