java一个代码可以有两个主程序嘛

java一个代码可以有两个主程序。根据查询相关公开信息显示，一个Java源文件中可以有多个主类，但是只能有一个公共类或者没有公共类，所谓主类就是函数运行的一个入口。

java的主程序入口，参数？

其中，Yippee是类名，public是它的修饰符，每个java文件中，最多可以有一个public的类，且这个类的名称要和java文件名一样。

main方法，是java程序的入口，String[] args，是它的参数，一个字符串数组。一楼的兄弟的说法是错误的。他运行没有结果，是因为这个程序他应该是在IDE工具中运行的，运行时，工具会自己给这个方法传入一个空数组的，数组长度为0，所以没有进去for循环，当然就没有结果了。

但是，如果你在命令行(windows系统的cmd)中运行，它就会让你输入一组参数，那时候就可以看到运行的结果了。

求一个简单java程序代码，谢谢

public class TestStar {

public static void main(String[] args) {

String star = "*";

for (int i = 0; i 5; i++) {

if (i == 0) {

System.out.print(" " + star);

System.out.println();

}

if (i == 1) {

for (int z = 0; z 4; z++) {

System.out.print(" " + star);

}

System.out.println();

}

if (i == 2) {

System.out.print(" ");

for (int x = 0; x 3; x++) {

System.out.print(" " + star);

}

System.out.println();

}

if (i == 3) {

for (int y = 0; y 2; y++) {

System.out.print(" " + star + " ");

}

}

}

}

}

是好使的 但是我没找到画五角星有什么规律（五角星好象不是正规图形吧？）如果还有什么要求的话 补充问题(如果是用*填充所有的东西 不包括 “ ”的话 我可以重新再给你写一个)

一个简单的Java程序代码？

package com.zpp;public class Charge {

public static void main(String [] args) {

if(args.length ==0) {

System.out.println("parameter error!");

System.out.println("java com.zpp.Charge [int]");

return;

}

int min = Integer.parseInt(args[0]);

double money = 0.0;

if (min = 0) {

money =0.0;

System.out.println("not money");

} else if (min = 60) {

money = 2.0;

} else {

money = 2.0 + (min - 60) * 0.01;

}

System.out.println("please pay: " + money);

}

} 编译：javac -d . Charge.java运行：java com.zpp.Charge 111

用JAVA做五子棋源代码

java网络五子棋

下面的源代码分为4个文件；

chessClient.java:客户端主程序。

chessInterface.java:客户端的界面。

chessPad.java:棋盘的绘制。

chessServer.java:服务器端。

可同时容纳50个人同时在线下棋，聊天。

没有加上详细注释，不过绝对可以运行，j2sdk1.4下通过。
