java - How to calculate tab length till the end of the String? -


this question has answer here:

i spliting string tab 

string s = "1"+"\t"+2+"\t"+3+"\t"+"4"; system.out.println("length : "+ s.split("\\t").length);

in case length 4. if remove last element 4 & give blank, like

string s = "1"+"\t"+2+"\t"+3+"\t"+""; system.out.println("length : "+ s.split("\\t").length);

in case got output 3. means not calculating last tab. in below case also, need length 4. scenario using in project & getting undesired result. please suggest me, how calculate entire length of tab delimited string, whether last element blank. such as, if case is,

string s = "1"+"\t"+2+"\t"+3+"\t"+""; system.out.println("length : "+ s.split("\\t").length);

then answer should 4 & if case is, 

string s = "1"+"\t"+2+"\t"+3+"\t"+"" + "\t"+ ""; system.out.println("length : "+ s.split("\\t").length);

then answer should 5.

please provide me appropriate answer.

to prevent split removing trailing empty spaces need use split(string regex, int limit) negative limit value 

split("\t", -1)

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
