problemSuppose there are arraysElement[]Array= {New Element(1),New Element(2),New Element(3)};How do you convert it to arraylistEssence Answerarrays asList array Arrays.aslist(new Element (1), new Element (2), new Element (3))However, there are some pits to be aware of:1. The list to be generated is fixed length. In other words, if you do add or remove to it, it will throw unsupportedoperationexception. 2, if you modify the value of the array, the corresponding value in the list will also

JS converts the date format to Yyyy-mm-dd HH:MM:SS

because of the background interface qualification, the form content must be converted to a JSON string submission, thus writing a function that transforms the form's form value into a JSON string. premise: The page introduces jquery directly below the codeOne, the code /** 表单序列化成json字符串的方法 */ function form2JsonString(formId) { var paramArray = $(‘#‘ + formId).serializeArray(); /*请求参数转json对象*/ var jsonObj={}; $(paramArray).each(function(){ jsonObj[this.name]=this.value; })

for compatibility reasons(although it is not encouraged in the new code). It is recommended that all people seeking this function useThe split method of String or the Java.util.regex packagepublic static string[] ConvertStrToArray2 (String str) {StringTokenizer st = new StringTokenizer (str, ",");//Put "," as a partition flag, and then assign the well-divided character to the StringTokenizer object.string[] Strarray = new String[st.counttokens ()];//evaluates the StringTokenizer method of the C

get a nan. The time to construct this is: 2013/03/08 00:00:00. You can also pass in hours, minutes, and seconds, but not just the hours, such as "2013/03/08 17", and the parameters will also get a Nan. The parameter can be "2013/03/08 17:20" or "2013/03/08 17:20:05", so that you can get the correct time, where if the number of seconds is not given, the default is 0.At this point the date data is obtained, if you want to get the so-called timestamp, you can:var time = Date.gettime ();This gets a

are several simple ways to get rid of fractional parts to convert decimals into integers, listed belowThe second kind: Two-time inversion, the same is the use of bit operation conversion principle. var integer = ~~decimal; 4 = ~~4.123The third type: mathematical functions that take integers up and down, Math.ceil and Math.floorvar integer = decimal >= 0? Math.floor (decimal): Math.ceil (decimal);Of course there are more complicated ways, but after the Robert Koritnik test, or with 0 or the way

In daily programming--including dialogs, relational databases, financial procedures, SMS programs, and all procedures for handling data files--it is common to control decimal places after decimals, and this article will explain how to use simple methods to control decimal places, and also to uncover a little bit of secrecy about string and data precision.The derivation of the problemIf you have a function that accepts a long double argument and converts
