I don't know how to parse this.
{
"code": 1000,
"result_msg": "Successful",
"result": "{\"birthDateAsText\":\"1999-12-3100:00:00.0\",\"birthPlace\":\"\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423,\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\",\"civilId\":\"123\",\"firstname\":\"\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\",\"gender\":\"\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\",\"lastname\":\"\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\",\"nationality\":\"\\u0423\\u0423\\u0423\\u0423\"}"
}
I tried this
if (resultObject.getInt("code") == 1000) {
JSONParse jsonParse = new JSONParse();
JSONObject object = resultObject.getJSONObject("result");
event.onSuccess(jsonParse.convertJson(object));
}
Actually I don't know how to parse and decode jsonobject. Please help me
Try this:
private static String decodeUnicode(String theString) {
char aChar;
int len = theString.length();
StringBuffer outBuffer = new StringBuffer(len);
for (int x = 0; x < len;) {
aChar = theString.charAt(x++);
if (aChar == '\\') {
aChar = theString.charAt(x++);
if (aChar == 'u') {
// Read the xxxx
int value = 0;
for (int i = 0; i < 4; i++) {
aChar = theString.charAt(x++);
switch (aChar) {
case '0':
case '1':
case '2':
case '3':
case '4':
case '5':
case '6':
case '7':
case '8':
case '9':
value = (value << 4) + aChar - '0';
break;
case 'a':
case 'b':
case 'c':
case 'd':
case 'e':
case 'f':
value = (value << 4) + 10 + aChar - 'a';
break;
case 'A':
case 'B':
case 'C':
case 'D':
case 'E':
case 'F':
value = (value << 4) + 10 + aChar - 'A';
break;
default:
throw new IllegalArgumentException(
"Malformed \\uxxxx encoding.");
}
}
outBuffer.append((char) value);
} else {
if (aChar == 't')
aChar = '\t';
else if (aChar == 'r')
aChar = '\r';
else if (aChar == 'n')
aChar = '\n';
else if (aChar == 'f')
aChar = '\f';
outBuffer.append(aChar);
}
} else
outBuffer.append(aChar);
}
return outBuffer.toString();
}
Uses:
JSONObject object = resultObject.getJSONObject("result");
System.out.println("Birthday: "+object.getString("birthPlace"))

Hello StackOverflow community, I've just begun to work with arrays and I was wondering how I can make the switch statement work with the values below. It's really irritating that it won't work considering the only error is constant expression required:
import java.lang.Character;
public class Ass11a {
public static char[] vowel = new char[4];
public static char[] consonant = new char[20];
public static char[] number = new char[9];
public static char[] punctuation = new char[10];
public static void main(String[] args) {
EasyReader console = new EasyReader();
System.out.print("Enter a character: ");
char input = console.readChar();
Character.toLowerCase(input);
vowel[0] = 'a';
vowel[1] = 'e';
vowel[2] = 'i';
vowel[3] = 'o';
vowel[4] = 'u';
consonant[0] = 'q';
consonant[1] = 'w';

consonant[9] = 'g';
consonant[10] = 'h';
consonant[11] = 'j';
consonant[12] = 'k';
consonant[13] = 'l';
consonant[14] = 'z';

You could use an enum like this
public enum Vowels {
A,E,I,O,U;
static boolean isVowel(char c) {
switch (c) {
case 'A': case 'a':
case 'E': case 'e':
case 'I': case 'i':
case 'O': case 'o':
case 'U': case 'u': return true;
}
return false;
}
static Vowels getVowel(char c) {
switch (c) {
case 'A': case 'a': return A;
case 'E': case 'e': return E;
case 'I': case 'i': return I;
case 'O': case 'o': return O;
case 'U': case 'u': return U;
}
return null;
}
}
and use it like
public static void main(String[] args) {
Scanner console = new Scanner(System.in);
while (console.hasNextLine()) {
String input = console.nextLine();
for (Character ch : input.toCharArray()) {
if (Vowels.isVowel(ch)) {
System.out.println(ch + " is vowel");
}
}
}
}
I am trying to change this from an input box into a Scanner class, but i am having trouble doing so.
Its a program that takes words and makes them into a phone number here is the code that does so. Any help would be greatly appreciated and if there is something that i can do in return i would gladly do so.
// declare imports
import java.util.Scanner;
import javax.swing.JOptionPane;
import java.util.*;
public class Telephone {
public static void main(String[] args) {
// ask for the phone number (in letters)
char letter;
String inputMessage = "Please enter the number in Letters " + "or enter '#' to stop the program ";
String inputString = JOptionPane.showInputDialog(inputMessage);
String outputString = "";
String outputMessage = "";
int digit = 0;
int x = 0;
for (int i = 0; i < inputString.length(); i++)
System.out.print(inputString.charAt(x)); {
while (inputString.charAt(x) != '#') {
letter = Character.toUpperCase(inputString.charAt(x));
x++;
// make sure its not a number
if (letter >= 'a' && letter <= 'z') if (letter >= 'A' && letter <= 'Z') {
digit++;
switch (letter) {
case 'A':
case 'B':
case 'C':
outputString += "2";
break;
case 'D':
case 'E':
case 'F':
outputString += "3";
break;
case 'G':
case 'H':
case 'I':
outputString += "4";
break;
case 'J':
case 'K':
case 'L':
outputString += "5";
break;
case 'M':
case 'N':
case 'O':
outputString += "6";
break;
case 'P':
case 'Q':
case 'R':
case 'S':
outputString += "7";
break;
case 'T':
case 'U':
case 'V':
outputString += "8";
break;
case 'W':
case 'X':
case 'Y':
case 'Z':
outputString += "9";
}
if (digit == 7) {
break;
}
if (digit == 3) {
outputString += "-";
}
}
inputMessage = "Enter another set of telephone letters";
}
JOptionPane.showMessageDialog(null, outputString, "Telephone Program", JOptionPane.PLAIN_MESSAGE);
}
Modify the line where you show the JOptionPane as follows,
//String inputString = JOptionPane.showInputDialog(inputMessage);
System.out.println(inputMessage);
Scanner sc = new Scanner(System.in);
String inputString = sc.nextLine();
so you could do the following,
package test;
import java.util.Scanner;
public class Telephone {
public static void main(String[] args) {
// ask for the phone number (in letters)
char letter;
String inputMessage = "Please enter the number in Letters " + "or enter '#' to stop the program ";
// String inputString = JOptionPane.showInputDialog(inputMessage);
System.out.println(inputMessage);
Scanner sc = new Scanner(System.in);
String inputString = sc.nextLine();
String outputString = "";
String outputMessage = "";
int digit = 0;
int x = 0;
for (int i = 0; i < inputString.length(); i++) {
System.out.print(inputString.charAt(x));
}
while (inputString != null && inputString.trim().length() > 0 && inputString.charAt(x) != '#') {
letter = Character.toUpperCase(inputString.charAt(x));
x++;
// make sure its not a number
// if (letter >= 'a' && letter <= 'z') {
if (x >= inputString.length()) {
x = 0;
System.out.println("\n" + outputString);
// JOptionPane.showMessageDialog(null, outputString, "Telephone Program", JOptionPane.PLAIN_MESSAGE);
// inputString = JOptionPane.showInputDialog(inputMessage);
System.out.println(inputMessage);
inputString = sc.nextLine();
} else if (letter >= 'A' && letter <= 'Z') {
digit++;
switch (letter) {
case 'A':
case 'B':
case 'C':
outputString += "2";
break;
case 'D':
case 'E':
case 'F':
outputString += "3";
break;
case 'G':
case 'H':
case 'I':
outputString += "4";
break;
case 'J':
case 'K':
case 'L':
outputString += "5";
break;
case 'M':
case 'N':
case 'O':
outputString += "6";
break;
case 'P':
case 'Q':
case 'R':
case 'S':
outputString += "7";
break;
case 'T':
case 'U':
case 'V':
outputString += "8";
break;
case 'W':
case 'X':
case 'Y':
case 'Z':
outputString += "9";
}
if (digit == 7) {
break;
}
if (digit == 3) {
outputString += "-";
}
}
// }
inputMessage = "Enter another set of telephone letters";
}
System.out.println("\n" + outputString);
// JOptionPane.showMessageDialog(null, outputString, "Telephone Program", JOptionPane.PLAIN_MESSAGE);

I have a small metod. It's get string with eng characters and return rus characters string (transliteration); But it's something wrong with it. I have no idea what. It's returned not string on Russian, but some junk like "[C#4057db80";
public String getRussianSting(String engString) {
char[] engCharString = engString.toLowerCase().toCharArray();
char[] rusCharString = new char[30];
for (int i = 0; i <= engCharString.length - 1; i++) {
if (engCharString[i] == ' ')
continue;
if (i + 1 <= engCharString.length - 1) {
if (engCharString[i] == 'c' && engCharString[i + 1] == 'h') {
rusCharString[i] = 'ч';
i++;
continue;
} else if (engCharString[i] == 's' && engCharString[i + 1] == 'h') {
rusCharString[i] = 'ш';
i++;
continue;
} else if (engCharString[i] == 't' && engCharString[i + 1] == 'z') {
rusCharString[i] = 'ц';
i++;
continue;
} else if (engCharString[i] == 'y' && engCharString[i + 1] == 'i') {
rusCharString[i] = 'ы';
i++;
} else if (engCharString[i] == 'y' && engCharString[i + 1] == 'e') {
rusCharString[i] = 'э';
i++;
continue;
} else if (engCharString[i] == 'y' && engCharString[i + 1] == 'u') {
rusCharString[i] = 'ю';
i++;
continue;
} else if (engCharString[i] == 'y' && engCharString[i + 1] == 'a') {
rusCharString[i] = 'я';
i++;
continue;
}
}
switch (engCharString[i]) {
case 'a':
rusCharString[i] = 'а';
break;
case 'b':
rusCharString[i] = 'б';
break;
case 'v':
rusCharString[i] = 'в';
break;
case 'g':
rusCharString[i] = 'г';
break;
case 'd':
rusCharString[i] = 'д';
break;
case 'e':
rusCharString[i] = 'е';
break;
case 'j':
rusCharString[i] = 'ж';
break;
case 'z':
rusCharString[i] = 'з';
break;
case 'i':
rusCharString[i] = 'и';
break;
case 'k':
rusCharString[i] = 'к';
break;
case 'l':
rusCharString[i] = 'л';
break;

rusCharString[i] = 'м';
break;
case 'n':

break;
case 'o':

break;

break;
case 'r':

break;
case 'f':

break;

rusCharString[i] = 'х';
break;
case '\'':
rusCharString[i] = 'ь';
break;
default:
break;
}
}
return rusCharString.toString();
}
return rusCharString.toString();
will return the String showing the object representation of the array. That is one major reason char[] is used for sensitive data instead of String.
try:
return new String(rusCharString);
The problem is that when you use the toString of an array, it will use the one that it inherits from Object class.
If you want to get a proper toString of an array, use java.util.Arrays.toString(rusCharString). The junk that you see is the hash code of that array.
If you want to print the hash code separately, use rusCharArray.hashCode()
I am using ISO9075 decoder in my application. When I try to decode the following String
ISO9075.decode("mediaasset_-g9mdob83oozsr5n_xadda")
its giving the following exception

I'm working with an application right now for our project in school. My application is about Resistor Color Code calculation. My codes are working, but in displaying the values, I used the value as string. My problem is I want to make my result value as 1.2K ohms, 1.5M ohm or 5.4M ohms, just like that. Because in my codes the result will display 1200 ohms, 1500K ohms or 5400K ohms. Help me Please. Thanks in advance for the help.
