使用类的构造函数创建一个实例

package test;

import java.lang.reflect.Constructor;

public class MyClass {
	private String str1;
	private String str2;
	public MyClass(String s1, String s2){
		str1 = s1;
		str2 = s2;
	}
	
	public static void main(String[] args){
		
		try {
			Class[] types= new Class[]{String.class, String.class};
			Constructor cons = MyClass.class.getConstructor(types);
			Object[] objs = new Object[]{"a", "b"};
			MyClass clazz = (MyClass) cons.newInstance(objs);
			System.out.println(clazz.toString());
			System.out.println(clazz.str1+" , "+clazz.str2);
		} catch (Exception e) { 
			e.printStackTrace();
		}  
		
	}
}
