merge two arrays in java

//Declare two arrays
int[] arr1 = {1,2,3};
int[] arr2 = {4,5,6};

//Declare the result array
int[] result = new int[arr1.length+arr2.length];

//Merge the two arrays
int i = 0;
for (int temp : arr1){
  result[i] = temp;
  i++;
}
for (int temp : arr2){
  result[i] = temp;
  i++;
}

//Print the result
System.out.println(Arrays.toString(result));

This code creates two integer arrays with values, arr1 and arr2, and then merges them together into a new array, result. We then iterate through each array, adding their values to the result array with an index of ‘i’ which is incremented at each iteration. Lastly, this code prints the resulting array to the console.
