Concatenates strings in a loop

[QiAnXinCodeSafe]

String objects are immutable. Concatenation and modification of string objects will eventually create a new string object.Concatenating strings in a loop creates a lot of objects and wastes the system's running time and space.You can use StringBuffer or StringBuilder instead of String for splicing

Lines 102 to 105 in 0e8cc0a

	String result = Integer.toString(value);
	for (int i = result.length(); i < codeLength; i++) {
	result = "0" + result;
	}

Thanks.

I doubt this'll be fixed, since who has a Blackberry in 2019?
