java - Word count in a string -


ok,now know question has been asked many times , answered too, came across question , wrote this(poor piece of) code without taking clue previous answeres,and although giving me correct output,i can't decide if correct. 

public class wordcount  { public static void main(string[] args) throws ioexception {     system.out.println("enter string");     bufferedreader br = new bufferedreader(new inputstreamreader(system.in));     string s1= br.readline();     s1 = s1+" ";     string ns = "";     int count = 0;     for(int = 0; < s1.length(); i++)     {         char ch = s1.charat(i);         if(ch == ' ')         {             //ns = ns+ch;             count++;         }         /*else         {             ns = ns+ch;         }*/     }     system.out.println("there "+count+" words in string");       }  } 

int linecount = yourstring.trim().split("\\s+").length;

the split() function returns array containing tokens made splitting string in specified way. take string, split spaces , since it's array - take length of it. that's need count words. (the regex \\s+ makes function split string @ every blank space, i.e., return array containing words.)

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
