You just need to know the number of bytes and multiply by 8. For example:

System.out.println("teste".getBytes().length * 8); //40

    What if the text is encoded in utf-8? There may be characters that occupy more than 8 bits.

    Anderson, so the "getBytes()" and not the String size directly.

    In fact, my fault.

Knowing that each sentence character has 8 bits just do this:

String str = "Algum texto";
int numDeBits = str.length * 8;

I don’t know if this is the java syntax but anything leaves a comment that I try to fix.

    accented characters can increase the size of bytes in a string, even with the same number of characters, so it is best to count the number of bytes in the string.

    ah then the answer from below is correct.
