Question

Write a program for the following.

Fill two arrays TA[ ] and TB[ ] of size 7 and type integer each. Create a third array TC[ ] that contains the elements of the second array (TB[ ]) followed by the elements of the first array (TA [ ]).

Input	TA[ ]	21	31	41	51	61	23	43
	TB[ ]	28	38	48	58	68	78	16
Output	TC[ ]	28	38	48	58	68	78	16
		21	31	41	51	61	23	43

        int TC[] = new int[14];        
        System.out.println("Enter 7 integers for array TA:");
        for (int j = 0; j < TA.length; j++) 
        {
            TA[j] = sc.nextInt();
        }
        System.out.println("Enter 7 integers for array TB:");
        for (int j = 0; j < TB.length; j++)
