Java reflection get implemented interfaces

Following two methods are used to get the implemented interfaces in java:

getGenericInterfaces() method is used to get the array of interfaces implemented by the class with generic type information.
getInterfaces() method is used to get the array of all the implemented interfaces.

Example

Shape.java

package com.w3spoint;
 
public interface Shape {
	public void drawShape(String color);
}

Rectangle.java

package com.w3spoint;
 
public class Rectangle implements Shape{
	private int defaultLength = 10;
	private int defaultWidth = 5;
 
	@Override
	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.w3spoint;
 
import java.util.Arrays;
 
public class ReflectionTest {
	public static void main(String args[]){
		try {
			Class c=Class.forName("com.w3spoint.Rectangle");  
			System.out.println(Arrays.toString(c.getInterfaces()));
		} catch (Exception e) {
			e.printStackTrace();
		}  
	}
}

Output

[interface com.w3spoint.Shape]
