求java经典小程序代码

代码如下：

public class HelloWorld {

public static void main(String []args) {

int a = 3, b = 7 ;

 System.out.println("Hello World!");

}

public static int f(int a, int b){

return a*a + a*b + b*b;

}

}

结果如下：

用java写一个小程序

java实现先输入10个int类型的参数，之后循环判断找到最大值和最小值，保存起来和其他的值进行比较。代码如下：

public class Test{

public static void main(String args[]){

int i,min,max;

int A[] = new int[10];

Scanner input=new Scanner(System.in);

for(int j=0,j10;j++){//输入10个数

System.out.println("请输入一个数字：");

int length=input.nextInt();//输入一个数字

A[i] =length;

}

min=max=A[0];

System.out.print("数组A的元素包括：");

int j =0;

int n =0 ;

for(i=0;iA.length;i++)

{

System.out.print(A[i]+" ");

if(A[i]max) // 判断最大值

j =i;

max=A[i];

if(A[i]min) // 判断最小值

min=A[i];

n =i

}

System.out.println("\n数组的最大值是："+max+".数组的位置是："+（j+1）); // 输出最大值和最大值的位置

System.out.println("数组的最小值是："+min+".数组的位置是："+（n+1）); // 输出最小值

}

}

谁能给个JAVA的小程序代码，越小越好！

这是我晓得的最简单的java小程序代码了你可以看看:

package com.kenki.emp;

import javax.servlet.*;

import javax.servlet.http.*;

import java.io.*;

import java.util.*;

import java.sql.SQLException;

import java.sql.*;

public class emp extends HttpServlet {

private static final String CONTENT_TYPE = "text/html; charset=GBK";

//Initialize global variables

public void init() throws ServletException {

}

//Process the HTTP Get request

public void doGet(HttpServletRequest request, HttpServletResponse response) throws

ServletException, IOException {

response.setContentType(CONTENT_TYPE);

PrintWriter out = response.getWriter();

String code = request.getParameter("code");

String name = request.getParameter("name");

String pay = request.getParameter("pay");

System.out.println("empcode:" + code);

System.out.println("name:" + name);

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

//创建驱动

new com.microsoft.jdbc.sqlserver.SQLServerDriver();

String strd =

"jdbc:microsoft:sqlserver://localhost:1433;databasename=emp_dates";

String username = "sa";

String pws = "";

try {

java.sql.Connection conn = java.sql.DriverManager.getConnection(

strd, username, pws);

String strs = "insert into emp values(?,?,?)";

java.sql.PreparedStatement pre = conn.prepareStatement(strs);

pre.setString(1, code);

pre.setString(2, name);

pre.setString(3, pay);

pre.execute();

pre.close();

conn.close();

//重定向至查询页面

out.println("成功保存！！");

response.sendRedirect("emp.html");

} catch (SQLException ss) {

ss.printStackTrace();

response.sendRedirect("/WebModule1/error.html");

}

}

//Process the HTTP Post request

public void doPost(HttpServletRequest request, HttpServletResponse response) throws

ServletException, IOException {

doGet(request, response);

}

//Clean up resources

public void destroy() {

}

}
