¿Cuál es la forma correcta de crear un objeto en Java?

What is the correct way to create an object in Java?

Java provides five ways to create an object.

1. Using new Keyword.
2. Using clone() method.
3. Using newInstance() method of the Class class.
4. Using newInstance() method of the Constructor class.
5. Using Deserialization.

Let’s see the simple code to convert String to Object in java.

1. public class StringToObjectExample{
2. public static void main(String args[]){
3. String s=”hello”;
4. Object obj=s;
5. System.out.println(obj);
6. }}

Parsing is to read the value of one object to convert it to another type. For example you may have a string with a value of “10”. Internally that string contains the Unicode characters ‘1’ and ‘0’ not the actual number 10. The method Integer. parseInt takes that string value and returns a real number.

Sure the string should be in proper format to return an object of Period class. This format is PnYnMnD . Where Y stands for “year”, M — for “month”, D — for “day”. N is a number corresponding to each period value. The method has one parameter — a text value. Parse () returns a Period value where the value of a string becomes a parameter.

When receiving data from a web server, the data is always a string. Parse the data with JSON.parse (), and the data becomes a JavaScript object. Use the JavaScript function JSON.parse () to convert text into a JavaScript object:

Both of them help to convert a string into a new Java 8 date API — java.time.LocalDate. This method parses a string using a specific formatter to obtain an instance of LocalDate. Here’s the syntax of the method: There are two parameters for the method — the text that will be parsed and the formatter a developer will apply.

JSON Processing in Java : The Java API for JSON Processing JSON.simple is a simple Java library that allow parse, generate, transform, and query JSON. Getting Started : You need to download the json-simple-1.1 jar and put it in your CLASSPATH before compiling and running the below example codes. For importing jar in IDE like eclipse, refer here.
