The following methods can be used for creating new instance of your classes, depending on your specific needs.
import java.lang.ClassLoader;import java.net.URLClassLoader;import java.net.URL;public class InstantiateClass { testFinally newInstance() throws Exception {
Second: Using the ClassLoader
ClassLoader loader = this.getClass().getClassLoader(); Class c = loader.loadClass("testFinally"); return (testFinally) c.newInstance(); } testFinally newInstance0() throws Exception {
Fourth: Using the ClassLoader
ClassLoader loader = InstantiateClass.class.getClassLoader(); Class c = loader.loadClass("testFinally"); return (testFinally) c.newInstance(); } testFinally newInstance1() throws Exception {
Fourth: Using the ClassLoader
testFinally tf = (testFinally) testFinally.class.newInstance(); return tf; } testFinally newInstance2() throws Exception {
Using the Class class
Class claz = Class.forName("testFinally"); testFinally tf = (testFinally) claz.newInstance(); return(tf); } testFinally newInstance3() throws Exception {
Using the ClassLoader
ClassLoader loader = new URLClassLoader( new URL[] { new URL(".") } ); Class c = loader.loadClass("testFinally"); return( (testFinally) c.newInstance()); } public static void main(String args[]) { try {
The conventional new method
testFinally tf0 = new testFinally(); tf0.main( new String[0] ); } catch(Exception ex) {ex.printStackTrace();} } }
