parseInt
public static final int parseInt(char[] digitChars, int offset, int len) Fast method for parsing integers that are known to fit into regular 32-bit signed int type. This means that length is between 1 and 9 digits (inclusive)Note: public to let unit tests call it

parseLong
public static final long parseLong(char[] digitChars, int offset, int len) -
inLongRange
public static final boolean inLongRange(char[] digitChars, int offset, int len, boolean negative) Helper method for determining if given String representation of an integral number would fit in 64-bit Java long or not. Note that input String must NOT contain leading minus sign (even if 'negative' is set to true).- Parameters:
negative
- Whether original number had a minus sign (which is NOT passed to this method) or not
-
parseDouble
- Throws:
NumberFormatException
