arrays - Incorrect output for Java in a Morse to English program -


here morse code english , vice versa assignment criteria:

  1. in morse code, | stands blank space.
  2. in morse code, blank space stands new letter or digit.

my code compiling correctly, output (after running it) incorrect.

// import scanner. import java.util.scanner  public class project1_szhu1249322 { public static void main(string[] args) {     scanner input = new scanner (system.in);     system.out.println("would translate 'morse code' english, or 'english' morse code? (enter 'morse code' or 'english'.)");     string unit1 = input.nextline();     system.out.println("enter string of " + unit1 + " characters (for english, numbers , letters, only): ");     string amountunit1 = input.nextline();     if (unit1 == "morse code")         toenglish(amountunit1);     else if (unit1 == "english")         tomorsecode(amountunit1);     else         system.out.println("invalid data. enter 'morse code' or 'english' without single quotes."); }  public static void tomorsecode(string english) {     // declare variables, arrays, , strings.     int = 0;     int l = english.length();     int i2 = 2 * i;     string[] loweralphabet = {"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","1", "2", "3", "4", "5", "6", "7", "8", "9", "0"};     string[] upperalphabet = {"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","1", "2", "3", "4", "5", "6", "7", "8", "9", "0"};     string[] morsecode = {".-", "-...", "-.-.","-..",".","..-.","--.","....","..",".---","-.-",".-..","--","-.","---",".--.","--.-",".-.","...","-","..-","...-",".--","-..-","-.--","--..",".----","..---","...--","....-",".....","-....","--...","---..","----.","-----"};     morsecode[i] = loweralphabet[i];     stringbuilder morsebuilder = new stringbuilder();      // loops , if statements result.

(i = 0; < l; i++)     {         i2 = / 2;         if (morse.charat(i) == '|')         {             englishbuilder.append(' ');         }         else             englishbuilder.append(morsecode[i2]);     }      morsecode[i] = loweralphabet[i];     // loops , if statements result.     (i = 0; < l; i++)     {         i2 = / 2;         if (morse.charat(i) == '|')         {             englishbuilder.append(' ');         }         else             englishbuilder.append(morsecode[i2]);     }      // display results.     system.out.println("the corresponding english " + englishbuilder + "."); } }

my output this:

would translate 'morse code' english, or 'english' morse code? (enter 'morse code' or 'english'.) english enter string of english characters (for english, numbers , letters, only):  invalid data. enter 'morse code' or 'english' without single quotes.

it not going right if-else branch. instead of going unit1 == "english", goes last else invalid data.

also, for loop in toenglish method, how should set i2? need / 2, if first character not blank space.

when creating translated string should use following instead of charat() = doesn't allow assignment:

stringbuilder bob = new stringbuilder();  (...){     if (...){         bob.append(character);     } } string english = bob.tostring();

also i2 equal 0.

there number of other small bugs in here. carry on debugging , solve them all.

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...

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)
