With this example we are going to demonstrate how to get an object’s class name. We
can get the class name for any object as shown in the steps below:
- We create a new Class object.
- We set the Class object to String.class and get its name using
getName()API method of Class. - We follow the same steps for other objects, such as java.awt.geom.Ellipse2D,
int,int[],String[]andVoid.Type.
Let’s take a look at the code snippet that follows:
package com.javacodegeeks.snippets.core;
import java.awt.geom.Ellipse2D;
public class GetAnObjectClassName {
public static void main(String[] args) {
Class<?> clazz = null;
clazz = String.class;
System.out.println("String: " + clazz.getName());
clazz = Ellipse2D.Double.class;
System.out.println("Ellipse2D.Double: " + clazz.getName());
clazz = int.class;
System.out.println("int: " + clazz.getName());
clazz = int[].class;
System.out.println("int[]: " + clazz.getName());
clazz = String[].class;
System.out.println("String[]: " + clazz.getName());
clazz = Void.TYPE;
System.out.println("Void.TYPE: " + clazz.getName());
}
}
Output:
String: java.lang.String
Ellipse2D.Double: java.awt.geom.Ellipse2D$Double
int: int
int[]: [I
String[]: [Ljava.lang.String;
Void.TYPE: void
This was an example of how to get an object’s class name in Java.
