In Java, primitive data types like int, double, boolean, etc., lack the functionalities provided by their corresponding wrapper classes (Integer, Double, Boolean, etc.). Wrapper classes offer additional methods and compatibility with collections and other Java APIs. Therefore, converting primitive types to wrapper classes is a common operation in Java programming. Here's how you can achieve it:

Using Constructors
One straightforward way to convert a primitive type to its wrapper class is by using the constructors provided by the wrapper classes. For example:

Using ValueOf() Method
Another convenient approach is to use the valueOf() method provided by the wrapper classes. This method accepts a primitive value as an argument and returns an instance of the corresponding wrapper class. Here's how you can use it:

Auto-Boxing (Implicit Conversion)
Java also supports auto-boxing, where primitive types can be automatically converted to their corresponding wrapper classes, and vice versa, without explicit constructor calls or valueOf() method invocations. This feature simplifies the code and enhances readability:

Conclusion
Converting primitive types to wrapper classes in Java is essential for leveraging the additional functionalities provided by wrapper classes and ensuring compatibility with various Java APIs and libraries. Whether you choose to use constructors, the valueOf() method, or rely on auto-boxing, Java offers multiple convenient methods to perform this conversion effortlessly.
