java編寫(xiě)火車(chē)售票系統(tǒng)

你說(shuō)的這個(gè)程序應(yīng)該是不難的，只不過(guò)N久沒(méi)有寫(xiě)過(guò)javaswing 了

創(chuàng)新互聯(lián)建站是一家專(zhuān)業(yè)提供尋甸企業(yè)網(wǎng)站建設(shè),專(zhuān)注與成都網(wǎng)站設(shè)計(jì)、成都做網(wǎng)站、H5響應(yīng)式網(wǎng)站、小程序制作等業(yè)務(wù)。10年已為尋甸眾多企業(yè)、政府機(jī)構(gòu)等服務(wù)。創(chuàng)新互聯(lián)專(zhuān)業(yè)網(wǎng)站建設(shè)公司優(yōu)惠進(jìn)行中。

還有就是java沒(méi)有多繼承的，只有多實(shí)現(xiàn)接口的

繼承的關(guān)鍵字是：extends

接口的關(guān)鍵字是：interface

java中，用static 變量，實(shí)現(xiàn)賣(mài)火車(chē)票，假如有三個(gè)窗口，每個(gè)窗口都在賣(mài)一輛火車(chē)的票， 買(mǎi)的票不能重復(fù)！

public class SaleTicket extends Thread{

static int mark=0;

static int ticket[]=new int [100];

int SaleTicketNo;

SaleTicket(int num){

SaleTicketNo=num;

}

public void run() {

// compute primes larger than minPrime

for(int i=0;i100;i++)

{

if(ticket[i]==0){

ticket[i]=1;

mark=mark+1;

System.out.println("售票機(jī)編號(hào)："+SaleTicketNo+" 票號(hào)："+i+" 張次："+mark);

}

}

}

}

public class Test {

/**

* @param args

*/

public static void main(String[] args) {

SaleTicket sale1=new SaleTicket(101);

SaleTicket sale2=new SaleTicket(102);

SaleTicket sale3=new SaleTicket(103);

SaleTicket sale4=new SaleTicket(104);

SaleTicket sale5=new SaleTicket(105);

sale1.start();

sale2.start();

sale3.start();

sale4.start();

sale5.start();

}

}

不考慮死鎖問(wèn)題

Java編程 假設(shè)有火車(chē)票1000張，創(chuàng)建10個(gè)線(xiàn)程模擬10個(gè)售票點(diǎn)，每個(gè)售票點(diǎn)100毫秒售出一張票。

package?tmp;

public?class?Test?{

private?static?int?k=0;//售出票數(shù)

private?static?int?count=1000;//總票數(shù)

private?static?synchronized?boolean?sell(int?n){

if(kcount){

k++;

System.out.println("第"+n+"售票點(diǎn)售出第"+k+"張票");

return?true;

}

return?false;

}

static?class?SellPot?extends?Thread{//售票點(diǎn)

int?n;//售票點(diǎn)編號(hào)

public?SellPot(int?n){

this.n=n;

}

public?void?run(){

while(sell(n)){

try?{

Thread.sleep(100);

}?catch?(InterruptedException?e)?{

e.printStackTrace();

}

}

}

}

public?static?void?main(String[]?args)?{

for(int?i=1;i=10;i++){

new?SellPot(i).start();

}

}

}

//銀行匯款

public?class?Test2?{

private?static?int?k=0;//總匯款

private?static?synchronized?void?send(int?m,int?i,int?n){

k+=m;

System.out.println("第"+n+"個(gè)顧客進(jìn)行第"+(i+1)+"次匯款,銀行接收總匯款"+k);
