Java equivalent of Visual Basic MidB$

Question

Is there an equivalent function in Java for MidB$?

The function returns the specified number of bytes from a string where the definition is MidB$(String As String, Start As Long, [Length] ) As String

It functions a bit similar to String.substring() but the length is defined in bytes.

Thanks.

Answer 1

You can try this:

int bytes = str.getBytes().length;

But this will be dependent on the character encoding of your platform.

More on getBytes().

Answer 2

private String MidB(String str, int start, int len) {
    byte[] bytes = str.getBytes()
    String ret = "";
    for (;start < len + start; start++)
       ret = ret + (char) bytes[start];
    return ret;
}

See if that works. And start won't get changed because primitives are passed by value in Java.
