For constructors handling we are going to use Constructors component. Constructors component uses to cache all constructors and all method handles for faster access. To start we need to add the following dependency to our pom.xml:
<dependency> <groupId>org.burningwave</groupId> <artifactId>core</artifactId> <version>12.64.3</version> </dependency>
… And to use Burningwave Core as a Java module, add the following to your module-info.java
:
requires org.burningwave.core;
Let’s take a look at the code now:
import static org.burningwave.core.assembler.StaticComponentContainer.Constructors; import org.burningwave.core.classes.MemoryClassLoader; public class ConstructorsHandler { public static void execute() { //Invoking constructor by using reflection MemoryClassLoader classLoader = Constructors.newInstanceOf(MemoryClassLoader.class, Thread.currentThread().getContextClassLoader()); //Invoking constructor with a null parameter value by using MethodHandle classLoader = Constructors.newInstanceDirectOf(MemoryClassLoader.class, null); } public static void main(String[] args) { execute(); } }
