How to clone array in java with this code

This code generates unsorted array. My question is how do I clone the generated array so I can reuse the unsorted array in different sorting algorithms.

public class UnsortedData{

private int [] coreData;  private int maxArraySize;  private int currentArraySize;    public UnsortedData(int size){      this.maxArraySize = size;      this.coreData = new int[this.maxArraySize];      this.currentArraySize = 0;  }    public boolean addData(int data){      if (currentArraySize < maxArraySize)      {          coreData[currentArraySize] = data;          currentArraySize++;          return true;      }      return false;  }  

public class dataSorting {

public static void main(String[] args) {      Random rand = new Random();      UnsortedData uD = new UnsortedData(1000000);        for (int x = 0; x < 50; x++) {          uD.addData(rand.nextInt(3000000));      }    }
