Length of byte[] array

Question

String str = "123456789";
byte[] bytes = str.getBytes();

I want to make the following loop

for (int j = 0; j < bytes.length(); j++) {
  b = bytes[j];
}

b will store each byte of my array, but I can't seem to get the length of the array correctly.

Error:cannot find symbol
Problem solved:  bytes.length instead of  bytes.length()

Answer 1

Use bytes.length without the ()

Answer 2

See the JLS - 10.7. Array Members:

The members of an array type are all of the following:

The public final field length, which contains the number of components of the array. length may be positive or zero.

length is a property, not a method. You should write:

bytes.length
