I want to take the values of the three arrays put them together into one array and output it but I have no idea how to do this. I would appreciate any answers to lead me in the right direction.

    // num is user entered as number of times to output

    int skuNum = new int[num];

    int letters = new int[4];

    int l_p_Num = new int[4];



    int count = 1;

    // Fill numbers array

    for (int s: skuNum) {

        System.out.print(String.format("%05d", (s + count)) + "     ");

        count++;

        // Fill letters array

        for(int i: letters) {

            i = (rnd.nextInt(26) + 'A');

            System.out.print((char)i);

        }

        System.out.print(" ");

        for(int q: l_p_Num) {

            q = rnd.nextInt(9) + 0;

            System.out.print(q);

        }

        System.out.println();

    }

You can use:

int arrays = {skuNum, letters, l_p_Num};

or

int arrays = new int {skuNum, letters, l_p_Num};

to create array of arrays and iterate through each array with for loops:

for (int i = 0; i < arrays .length; i++) {

   // each array from arrays

   for (int j = 0; j < arrays [i].length; j++) {

       //each int value from each array

       System.out.println(arrays[i][j]);

   } 

}

To display the result in your "00001 DVAH 4238" format

for (int i=0; i<skuNum.length; i++) {

   String row = String.valueOf(skuNum[i]) + String.valueOf(letters[i]) + String.valueOf(l_p_Num[i]);

   System.out.println(row);

}

A possible java 8 solution is the following:

    int skuNum = new int[num];

    int letters = new int {1, 2, 3, 4};

    int l_p_Num = new int {11, 12, 13, 14};





    IntStream joined = IntStream.concat(IntStream.concat(IntStream.of(skuNum), IntStream.of(letters)), IntStream.of(l_p_Num));



    System.out.println(joined

            .boxed()

            .map(String::valueOf)

            .collect(Collectors.joining(",")));

Declare a new int array to hold all the numbers and then use System.arraycopy() to copy the smaller arrays into the result array:

int skuNum = new int[num]; // 1, 2

int letters = new int[4];  // 4, 5, 6, 7

int l_p_Num = new int[4];  // 9, 8, 7, 6



int result = new int[num + 8];

System.arraycopy(skuNum, 0, result, 0, num);

System.arraycopy(letters, 0, result, num, 4);

System.arraycopy(l_p_Num, 0, result, num + 4, 4);



System.out.println(Arrays.toString(result));

will output:

[1, 2, 4, 5, 6, 7, 9, 8, 7, 6]

So this is without the Java generics, just with for loops

int skuNum = {1,2,3};

    int letters = {4,5,6};

    int l_p_Num = {7,8,9};



    int finalInt = new int[skuNum.length+letters.length+l_p_Num.length];



    for (int i = 0; i<skuNum.length;i++) {

        finalInt[i] =skuNum[i];



    }



    for (int i = 0; i<letters.length;i++) {

        finalInt[i+skuNum.length] =letters[i];



    }

    for (int i = 0; i<l_p_Num.length;i++) {

        finalInt[i+skuNum.length+letters.length] =l_p_Num[i];



    }

    for (int i : finalInt)

        System.out.print(i);

Result:

123456789

If you want to have strings in it see this code:

        int skuNum = {1,2,3};

    String letters = {"asd","asd","aefuh"};

    int l_p_Num = {7,8,9};



    String finalArray = new String[skuNum.length+letters.length+l_p_Num.length];



    for (int i = 0; i<skuNum.length;i++) {

        finalArray[i] =String.valueOf(skuNum[i]);



    }



    for (int i = 0; i<letters.length;i++) {

        finalArray[i+skuNum.length] =letters[i];



    }

    for (int i = 0; i<l_p_Num.length;i++) {

        finalArray[i+skuNum.length+letters.length] = String.valueOf(l_p_Num[i]);



    }

    for (String st : finalArray)

        System.out.print(st);
