java - Arrayelements as counters -


i'm learning java , have misunderstanding array elements:

import java.util.random; class 1 {   public static void main (string[]args) {     random r1 = new random();     int mat [] = new int [6];     ( int chance =0; chance<99; chance++ ) {                     ++mat[1+r1.nextint(5)];              }     system.out.println("m\tnumber");     for(int m =1;m <mat.length;m++) {              system.out.println(m  + "\t" + mat[m]);     }   } }

and after running code got like: 

  m number     1   30     2   15     3   17     4   23     5   14

i did lot of attempts , number <=20, bit confusing me cause assighn chance <99 hence asume should bigger number in general. point on mistake?

i think there no mistake. numbers 20 because:

you repeat following sequence 99 times: 1. 1 random(one of six) element array. 2. increase element value (plus one).

let's assume (of course doesn't) random method works in way gets 99 execution : 20 times value 0 20 times value 1 20 times value 2 20 times value 3 20 times value 4 19 times value 5

so get: 20 in first array element 20 in second array element , on...

so, bigger number need decrease array length or change condition in loop bigger "chance" number (in case: ( int chance =0; chance<200; chance++ ) ).

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
