clone array java code example

Example 1: java copy array

// Shallow copy
int[] src = {1,2,3,4,5};
int[] dst = Arrays.copyOf(src, src.length);

// Deep copy
int[] dst2 = new int[src.length];
for(int i = 0; i < src.length; i++){
	dst2[i] = src[i];
}

Example 2: java copy array

int[] a = {1, 2, 3};      
int[] b = a.clone();

Example 3: copy array in java

int[] src  = new int[]{1,2,3,4,5};
int[] dest = new int[5];

System.arraycopy( src, 0, dest, 0, src.length );

Example 4: java copy array

int[] a = {1,2,3,4,5};
int[] b = Arrays.copyOf(a, a.length);

Example 5: how to copy array in java

// method 
public static int [] copyArray(int [] arr){
      int [] copyArr = new int[arr.length];
      for (int i = 0; i < copyArr.length; i++){
            copyArr[i] = arr[i];
       }
      return copyArr;
}

// Arrays. method 
int[] copyCat = Arrays.copyOf(arr, arr.length);

// System 
System.arraycopy(x,0,y,0,5); // 5 is array's length 

// clone 
y = x.clone();

Example 6: how to clone array in java

// A Java program to demonstrate array copy using clone()
public class Test {
    public static void main(String[] args)
    {
        int a[] = { 1, 8, 3 };
        int b[] = a.clone();
    }
}
