String userdata = /*value from gui*/ int val; try { val = Integer.parseInt(userdata); } catch (NumberFormatException nfe) { // bad data - set to sentinel val = Integer.MIN_VALUE; } I could use a regex to check if it's parseable, but that seems like a lot of overhea...
public static int parseIp(String address) { int result = 0; // iterate over each octet for(String part : address.split(Pattern.quote("."))) { // shift the previously parsed bits over by 1 byte result = result << 8; // set the low order bits to the current octet result |= In...
jdk中的Integer类是int对象的包装类,正常的Integer占用内存开销要比int大,比例大概是1:4 。 今天分享的代码是Integer类中的静态方法parseInt(String, int)。这个方法众所周知, 甚至在我们一开始学习编程时就尝试的写过这样的代码,一个正常的思路: 遍历输入的字符数组(java的字符串就是一个字符数组), 然后parse每个...

parsing java卡死 parseint java parseInt和valueOf 我们平时应该都用过或者见过parseInt和valueOf这两个方法。一般我们是想把String类型的字符数字转成int类型。从这个功能层面来说,这两个方法都一样,都可以胜任这个功能。 但是,我们进入源码,看下Integer类下这两个方法...

Assume an incoming message that contains a ‘severity’ field that stores severity as one of three words: high, medium and low. But we want to store a normalized severity value as an integer ranging from 0 to 9. We might use aCASE_SWITCHstatement paired with a list ofCASEstatements to pe...
