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);
    }

}

      

输出：

Jerry: false
