Here is my code:
for (String toEmail : toEmailList)
{
Log.i("GMail","toEmail: "+toEmail);
emailMessage.addRecipient(Message.RecipientType.TO, new InternetAddress(toEmail));
}
Please give me some suggestion about this.
Python is all about objects thus the objects can be directly converted into strings using methods like str() and repr(). Str() method is used for the conversion of all built-in objects into strings. Similarly, repr() method as part of object conversion method is also used to convert an object back to a string.
The answer is option D (str(x)). str(x) converts the object to a string in python.
Example 1: Convert Object to String Using JSON. stringify() method is used to convert an object to a string. The typeof operator gives the data type of the result variable.
To convert any object to string there are several methods in Java
String convertedToString = String.valueOf(Object); //method 1
String convertedToString = "" + Object; //method 2
String convertedToString = Object.toString(); //method 3
I would prefer the first and third
EDIT
If working in kotlin, the official android language
val number: Int = 12345
String convertAndAppendToString = "number = $number" //method 1
String convertObjectMemberToString = "number = ${Object.number}" //method 2
String convertedToString = Object.toString() //method 3
If the class does not have toString()
method, then you can use ToStringBuilder
class from org.apache.commons:commons-lang3
pom.xml:
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.12</version>
</dependency>
code:
ToStringBuilder.reflectionToString(yourObject)
I am try to convert Object type variable into string using this line of code
try this to convert object value to string:
Java Code
Object dataobject=value;
//convert object into String
String convert= String.valueOf(dataobject);
"toString()" is Very useful method which returns a string representation of an object. The "toString()" method returns a string reperentation an object.It is recommended that all subclasses override this method.
Declaration: java.lang.Object.toString()
Since, you have not mentioned which object you want to convert, so I am just using any object in sample code.
Integer integerObject = 5;
String convertedStringObject = integerObject .toString();
System.out.println(convertedStringObject );
You can find the complete code here. You can test the code here.
I've written a few methods for convert by Gson library and java 1.8 .
thay are daynamic model for convert.
string to object
object to string
List to string
string to List
HashMap to String
String to JsonObj
//saeedmpt
public static String convertMapToString(Map<String, String> data) {
//convert Map to String
return new GsonBuilder().setPrettyPrinting().create().toJson(data);
}
public static <T> List<T> convertStringToList(String strListObj) {
//convert string json to object List
return new Gson().fromJson(strListObj, new TypeToken<List<Object>>() {
}.getType());
}
public static <T> T convertStringToObj(String strObj, Class<T> classOfT) {
//convert string json to object
return new Gson().fromJson(strObj, (Type) classOfT);
}
public static JsonObject convertStringToJsonObj(String strObj) {
//convert string json to object
return new Gson().fromJson(strObj, JsonObject.class);
}
public static <T> String convertListObjToString(List<T> listObj) {
//convert object list to string json for
return new Gson().toJson(listObj, new TypeToken<List<T>>() {
}.getType());
}
public static String convertObjToString(Object clsObj) {
//convert object to string json
String jsonSender = new Gson().toJson(clsObj, new TypeToken<Object>() {
}.getType());
return jsonSender;
}
