Pad a binary String equal to zero (“0”) with leading zeros in Java

Question

Integer.toBinaryString(data)

gives me a binary String representation of my array data.

Answer 1

String dataStr = data == 0 ? "00" +   Integer.toBinaryString(data)  : Integer.toBinaryString(data);

edit: noticed the comment about dynamic length: probably some of the other answers are more suited:)
