Contoh Validasi (JAVA)

kebetulan dapet soal pada saat interview di salah satu startup terkemuka di indonesia terkait validasi. jadi disini ada data dengan 5 kolom:

1 : id transaksi
2 : sumber transaksi
3 : tujuan transaksi
4 : nilai transaksi
5 : tanggal transaksi

kebetulan tes nya diminta untuk membuat 4 validasi:

1 : cek transaksi yang duplikasi
2 : cek transaksi dengan sumber dan 1 tanggal transaksi yang lebih besar 300
3 : cek transaksi dengan tujuan dan 1 tanggal transaksi yang lebih besar 300
4 : cek transaksi dengan sumber, tujuan dan 1 tanggal transaksi yang lebih besar 300

kurang lebih source code nya:

import java.util.HashMap;
 
public class Tes2 {
	public static void main(String args[]) {
		String[] data = {
				"TRX1;SOURCE1;DEST1;100;20171201",

			}

			}
 
			// output validasi
			if (hmValidasi1.get(s) > 1) {
				System.out.println(s + " : duplicate validation");
