In this example we shall show you how to get the class of an Object. To get the class that represents an Object one should perform the following steps:

  • Create a newObject.
  • Get the class of the Object, usinggetClass() API method ofObject. It returns the runtime class of this Object. The returned Class object is the object that is locked by static synchronized methods of the represented class.
  • Get the name of the class represented by this Class object, as a String, usinggetName() API method ofClass,

as described in the code snippet below.  

package com.javacodegeeks.snippets.core;  public class GetClassFromObject {public static void main(String[] args) {    String s = "";    Class c = s.getClass();    System.out.println(c.getName());    c = new GetClassFromObject().getClass();    System.out.println(c.getName());}}

Output:

java.lang.StringGetClassFromObject

  
This was an example of how to get the class of an Object in Java.
