Java reflection get package name


The java.lang.Class provides the methods to examine the runtime properties of the object including its members and type information. For every type of object, the JVM instantiates an immutable instance of java.lang.Class. Using reflection, we can get the metadata of a class at run time.

The getPackage() is used to get the package of the class.

Example

Rectangle.java

package com.codesjava;
 
public class Rectangle {
	private int defaultLength = 10;
	private int defaultWidth = 5;
 
	public void drawShape(String color) {
		System.out.println("Rectangle create with following properties: ");
		System.out.println("Length: " + defaultLength);
		System.out.println("Width: " + defaultWidth);
	}
 
}

ReflectionTest.java

package com.codesjava;
 
public class ReflectionTest {
	public static void main(String args[]){
		try {
			Class c=Class.forName("com.codesjava.Rectangle");  
			System.out.println(c.getPackage());
		} catch (Exception e) {
			e.printStackTrace();
		}  
	}
}

Output

package com.codesjava
