If you execute the following function, what do you think should be the size of the 'def' byte array?
The logic is really simple: an input as byte array that have two elements, then create a string out of this with 'UTF-8' encoding, then create another byte array using this string with the same UTF-8 encoding.
public static void testStringUTF8() {
byte[] abc = new byte[2];
abc[0] = 31;
abc[1] = -117;
try {
String stringAbc = new String(abc, "UTF-8");
byte[] def = stringAbc.getBytes("UTF-8");
if (def != null) {
System.out.println("size of output byte array:" + def.length); //print the array size
}
System.out.println(def[1]); //print the second element of the output byte array
System.out.println(abc[1]); //print the second element of the input byte array
} catch (Exception e) {
e.printStackTrace();
}
}
