Java对象和类

一 、创建ClassObject.java

public class ClassObject {
    int myclass;
    /* creat class and object to use */
    public ClassObject(String name) {
        System.out.println(name+"1");
    }

    public ClassObject(int ss) {
        System.out.println("myclass"+ss);
    }
    /* method to use  */
    public void setTime(int time) {
        myclass = time;
    }

    public void getTime() {
        System.out.println("myclass"+myclass);
        //return baijie;
    }

    /* main */
    public static void main(String[] args) {
        ClassObject myClassObject = new ClassObject("myclass");
        ClassObject myClassObject_2 = new ClassObject(2);
        myClassObject.setTime(3);
        myClassObject.getTime();                                                                                                                                                                             
        System.out.println("myclass"+myClassObject.myclass);
    }
}

二、运行java

    执行命令：

javac ClassObject.java
