clocks.java

java基础教程以及代码 java base document and code

// 简单类演示，可以看出和C++很一致

public class Clocks
{
	public static void main(String [] args)
	{
		Clock [] cks;
		cks=new Clock[10];   // 这是对数组的初始化
		int i;
		for (i=0;i<10;i++) cks[i]=new Clock();  // 这是对对象的初始化
		cks[4].setTime(3,32,8);
		for (i=0;i<10;i++) System.out.println(cks[i]);
	}
}

class Clock
{
	public int h,m,s;
	public Clock() { System.out.println("Creation!"); h=m=s=0;}
	public void finalize() {System.out.println("Decreation!");}
	public String toString() {String st=""+h+":"+m+":"+s; return st;}

	public void showTime() {System.out.println(""+h+m+s);}
	public void setH(int hour) {this.h=hour;}
	public void setM(int mins) {this.m=mins;}
	public void setS(int secs) {this.s=secs;}
