Lead and Zinc

After the ore has been concentrated at a mill near the mine, the lead concentrates are shipped to a smelter. Here, in the case of galena, the first step involves removing the sulfur from the mineral. Roasting in air causes the sulfur to be converted to sulfur dioxide gas. This roasting process converts the lead sulfide to lead oxide.

How to remove leading zeros from alphanumeric text?

· How about the regex way: String s = "001234a"; s = ("^0*", ""); The ^ anchors to the start of the string (I'm assuming from context your strings are not multiline here, otherwise you may need to look into A for start of input rather than start of line). The 0* means zero or more 0 characters (you could use 0+ as well). The replaceFirst just replaces all those 0 .
