Examples of java.lang.reflect.Constructor.newInstance()

java.lang.reflect.Constructor.newInstance()
Uses the constructor represented by this Constructor object to create and initialize a new instance of the constructor's declaring class, with the specified initialization parameters. Individual parameters are automatically unwrapped to match primitive formal parameters, and both primitive and reference parameters are subject to method invocation conversions as necessary.
If the number of formal parameters required by the underlying constructor is 0, the supplied initargs array may be of length 0 or null.
If the constructor's declaring class is an inner class in a non-static context, the first argument to the constructor needs to be the enclosing instance; see The Java Language Specification, section 15.9.3.
If the required access and argument checks succeed and the instantiation will proceed, the constructor's declaring class is initialized if it has not already been initialized.
If the constructor completes normally, returns the newly created and initialized instance. @param initargs array of objects to be passed as arguments tothe constructor call; values of primitive types are wrapped in a wrapper object of the appropriate type (e.g. a float in a {@link java.lang.Float Float}) @return a new object created by calling the constructorthis object represents @exception IllegalAccessException if this Constructor objectenforces Java language access control and the underlying constructor is inaccessible. @exception IllegalArgumentException if the number of actualand formal parameters differ; if an unwrapping conversion for primitive arguments fails; or if, after possible unwrapping, a parameter value cannot be converted to the corresponding formal parameter type by a method invocation conversion; if this constructor pertains to an enum type. @exception InstantiationException if the class that declares theunderlying constructor represents an abstract class. @exception InvocationTargetException if the underlying constructorthrows an exception. @exception ExceptionInInitializerError if the initialization provokedby this method fails.
