I am new to Java. Please help me. Below is the string after implementing HTTP POST method as a response:
{"Result":"{ \"Search\": [ { \"Code\": \"200\" }, { \"Message\": \"Fetched successfully\" }, { \"Name\": \"1\", \"id\": \"166\", \"PID\": \"162\" } ]}"}
Now i want to get only Names in the given String and form a Stirng[] of Names. Please help me.
You need to first parse this JSON and then iterate through it

After you have parsed this JSON text, then its a matter of iterating through the object and keep pushing the values into arraylist
Once you got the arraylist, then you can convert it to a String array
You can use the below code to extract the names and their values
List<String> nameValues = new ArrayList<String>();
Matcher matcher1 = Pattern.compile("\\\\\"Name\\\\\":\\s\\\\\"[^,}\\]]+\\\\\"").matcher(value);
while (matcher1.find()) {
String keyValuePair = matcher1.group();
String[] keyValue = keyValuePair.split(":");
String val = keyValue[1].trim();
System.out.println(keyValue[0]);
System.out.println(">" + val + "<");
nameValues.add(val.substring(2, val.length() - 2));
}
System.out.println(nameValues);
Here use this one:
public class CStringToCharArray {
public static void main(String[] args) {
String testString = "This Is Test";
char[] stringToCharArray = testString.toCharArray();
for (char output : stringToCharArray) {
System.out.println(output);
}
}
}
\"elements, there should be none of these, just the double-quotes, no slashes)GetEpExamsResultas a string, then once again parse this string as JSON to get your data in the proper format. however, you preferred to accept the hacky and kludgy answer, that took several tries to get it working and that will eventually stop working at any moment in the future. well, good luck with your choice =)
