Do we any lib or method which will tell us the size of string value in bytes , am checking for size not length .

can anyone help me on this

.getBytes().length gives the length of the string not size , for example

String s = "Apple"

s.getBytes().length returns 5 , i think this length not size

There is a method called getBytes() string.getBytes().length will give number of bytes used by the string to store the value. In normal circumstances each character can take 2 bytes each to store a unicode value.

    final String string = "Hello World";

    final byte[] utf8Bytes = string.getBytes("UTF-8");
    System.out.println(utf8Bytes.length);
