class myframe extends Frame implements WindowListener
{
mypanel panel;
myframe()
{
setLayout(null);
panel = new mypanel();
add(panel);
panel.setBounds(0,23, 360, 360);
setTitle("单人版五子棋");
setBounds(200, 200, 360, 383);
setVisible(true);
addWindowListener(this);
}
public void windowClosing(WindowEvent e)
{
System.exit(0);
}
public void windowDeactivated(WindowEvent e){}
public void windowActivated(WindowEvent e){}
public void windowOpened(WindowEvent e){}
public void windowClosed(WindowEvent e){}
public void windowIconified(WindowEvent e){}
public void windowDeiconified(WindowEvent e){}
}
public class mywindow
{
public static void main(String argc [])
{
myframe f = new myframe();
}
}
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：
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
}
}
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() {
}
}
