how to create a duplicate array in 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();
