一个错误， NetBeans 显示找不到 main.java. Exception in thread "main" java.lang.UnsupportedOperationException: Not yet implemented

import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
//import javax.crypto.spec.IvParameterSpec;
//import javax.crypto.Cipher;

public class Main {

public static void main(String[] unused) throws Exception {

String xform = "Id\tProject name\titem amount\tCost\n1\tAC peanut375GM\t2\t"
+"$3.00\n2\tSweet photatoes\t1kg\t$2.48\nTotal cost\t\t$8.48";

// String xform = "DES/ECB/PKCS5Padding";

// Generate a secret key
KeyGenerator kg = KeyGenerator.getInstance("DES");
kg.init(56); // 56 is the keysize. Fixed for DES
SecretKey key = kg.generateKey();

//Ism not sure what the text of dataBytes below
byte[] dataBytes =
"J2EE Security for Servlets, EJBs and Web Services".getBytes();

byte[] encBytes = encrypt(dataBytes, key,xform);

System.out.print(dataBytes);
byte[] decBytes = decrypt(encBytes, key, xform);
System.out.print(decBytes);
}
}
private static byte[] decrypt(byte[] encBytes, SecretKey key, String xform) {
throw new UnsupportedOperationException("Not yet implemented");
}

private static byte[] encrypt(byte[] dataBytes, SecretKey key, String xform) {
throw new UnsupportedOperationException("Not yet implemented");
}
}
