package com.luoluo.cc;

public class meReflect {

@SuppressWarnings("unused")

private void t(int n){

System.out.println("类的私有方法");
}

private static void tt(){

System.out.println("类的静态私有方法");
}

}

利用反射机制

package com.luoluo.testCc;

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

import com.luoluo.cc.meReflect;


public class testMeReflect {
    
public static void main(String[] args) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException{

meReflect re = new meReflect();

Method m;

//Class cls = re.getClass();
// 获取指定的方法，调用re类的私有方法；  
try {

m = re.getClass().getDeclaredMethod("t",int.class);
m.setAccessible(true);//压制java的访问修饰符；
m.invoke(re, 1);

} catch (NoSuchMethodException | SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

}
