java shuffle an ordered array

1. Add a sequential array to the collection


2. You can use the shuffle() method of the collection helper class Collections

3. Traverse the input collection with hasNext() and next() methods

public class Shuffle {  
      

    public static void main(String[] args) { 

        shuffle(); ------- call this method
    }  
      //define this static method

    public static void shuffle(){  

       int[] x = {1,2,3,4,5,6}; --------Define an ordered array of int type and initialize
        List list = new ArrayList(); ---- ----Create a list collection to store the array
        for(int i = 0;i < x.length;i++){ -------traverse the array
            System.out.print(x[i]+", ");  
            list.add(x[i]); ------- add array elements to the collection storage
        }  
        System.out.println();  
          
        Collections.shuffle(list); ------ Call  Collections.shuffle(); method to shuffle the array order
          
        Iterator ite = list.iterator(); -------Use iterator to traverse the collection
        while(ite.hasNext()){  
            System.out.print(ite. next().toString()+", "); ------ output collection
        }  
    }
