How to convert Java string to object?

In order to convert a string into an object, there are several ways to achieve this in Java.

1. Using constructor functions: If the target object has a constructor function with a string parameter, you can use that constructor function to create the object. For example, if the target object is a Person class with a constructor function that takes a string parameter, you can convert the string to an object using the following method:

String str = "John";
Person person = new Person(str);

1. The valueOf() method can be used in many Java classes to convert a string into an object. For example, if the desired object is an integer, you can use the valueOf() method from the Integer class to convert the string into an integer object.

String str = "100";
Integer number = Integer.valueOf(str);

1. Reflection: By utilizing Java’s reflection mechanism, objects can be created dynamically based on the class name provided as a string. For instance, to convert a string into an object if the target object is an instance of a class, the following method can be used:

String className = "com.example.MyClass";
Class<?> clazz = Class.forName(className);
Object obj = clazz.newInstance();

Please note that the target class must have a parameterless constructor when using reflection.

There are several common ways to convert a string to an object, and the specific method to use depends on the type of the target object and the available methods.
