通过反射的方式调用Java类的方法

package reflection;
import java.lang.reflect.Method;
public class DuckType {
  public void print(boolean flag){
    System.out.println("Jerry: " + flag);
  }
  public  void reflectCall(Object obj){
    try {
      Class<?> clz = obj.getClass();
      Method m = clz.getMethod("print", boolean.class);
      m.invoke(obj, false);
    } catch ( Exception e){
      e.printStackTrace();
    }
  }
  public static void main(String[] args) {
    DuckType tool = new DuckType();
    tool.reflectCall(tool);
  }
}

Jerry: false
