[Solved] How to concatenate two arrays into 1 single array using java? [duplicate]

1. Make a for-loop an iterate over Array1 and Array2
2. Do Integer.parseInt(String.valueOf(Array1[i])+String.valueOf(Array2[i]));
3. Fill the Array3 in the for-loop with the calculated valued.

That’s it.

    int[] Array1 = new int[] {3,3,3};
    int[] Array2 = new int[] {3,2,1};
    int[] Array3 = new int[Array2.length];

    for(int i = 0; i<Array1.length; i++) {
        Array3[i] = Integer.parseInt(String.valueOf(Array1[i])+String.valueOf(Array2[i]));
    }

Output:

Array3[] = {33,32,31}
