Apr 15, 2025 · A Wrapper class in Java is one whose object wraps or contains primitive data types. When we create an object in a wrapper class, it contains a field, and in this field, we can store primitive data types. In other words, we can wrap a primitive value into a wrapper class object. Let's check on the wr

In this tutorial, we will learn about the Java Wrapper class with the help of examples. The wrapper classes in Java are used to convert primitive types (int, char, float, etc) into corresponding objects.

Java Wrapper Classes. Wrapper classes provide a way to use primitive data types (int, boolean, etc..) as objects. The table below shows the primitive type and the equivalent wrapper class:
