public class Main {
public static void main(String[] args) {
Student student = new Student();
student.nNum2=20;
}
}
封裝模塊下的com.bluelesson包中的Student類
package com.bluelesson;

*/
public class Student {
int nNum1;
public int nNum2;
private int nNum3;
protected int nNum4;
}
封裝模塊下的com.bluelesson包中Te類
package com.bluelesson;
/**

*/
public class Te {
public void Test(){
Student student = new Student();
student.nNum1 =10;//默認的
student.nNum2 =10;//公有的
student.nNum4=10;//保護的
}
}
