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 wrapper classes in Java with examples.

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: Primitive Data Type
