import java.awt.Color;

import java.awt.Font;

import java.awt.Graphics;

public class DrawString extends Applet {

public void paint(Graphics g)

{

g.setFont(new Font("宋体",Font.BOLD,36));

g.setColor(Color.green);

g.drawString("这是一个Java Applet程序",5,30);

g.setColor(Color.red);

如何找用java跟mysql写的调查问卷的源代码

首先创建一个连接工厂import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.Statement;public class ConnectionFactory {

private Connection conn=null;

private Statement stmt=null;

private ResultSet rs=null;

public ConnectionFactory() {

super();

怎么用Java程序编写个调查问卷

1------------------------------------------------------------------------------

import java.util.Scanner;

public class Main {

public static void main(String[] args) throws IOException{

Scanner scan = new Scanner(System.in);

System.out.println("输入一个整数：");

int num = scan.nextInt();

char[] numChar = Integer.toString(num).toCharArray();

for(int i = 0;inumChar.length; i++) {

System.out.println(numChar[i]);

}

}

}

2-----------------------------------------------------

public class Text2 {

public static void main(String[] args) {

int j = 0, k = 0;

for (int i = 1 ; i = 100; i++) {

if (i % 2 == 0) {

j += i ;

} else {

k += i;

}

}

System.out.println("偶数和为：" + j);

System.out.println("奇数和为：" + k);

}

}

3------------------------------------------------------------------------

import java.util.*;

public class Test {

public static void main(String[] args) {

Scanner san = new Scanner(System.in);

int aint = 0;

System.out.print("请输入一个整数: ");

aint = san.nextInt();

System.out.println(aint + "的二进制表示为: " + Integer.toBinaryString(aint));

}

}

4--------------------------------------------------------------------------------

public class text {

public static void main(String args[]) {

text t = new text();

System.out.print(t.sum());

}

public int sum(){

int a = 0;

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

int b = 1;

for (int j = 1; j =i; j++) {

b = b*j;

}

a=a+b;

}

return a;

}

}

4.2----------------------------------------------------------

import java.io.*;

public class jiecheng

{

public static long fac(int n)

{long res=1;

for(int k=2;k=n;k++)

res*=k;

return res;}

public static void main(String args[]) throws IOException

{long sum=0;int i=1,n=20;

for(i=1;i=n;i++)

sum+=fac(i);

System.out.println("前"+n+"项阶乘的为："+sum);

}

}

5--------------------------------------------------------------------------

public class Dy3 {

public static void main(String[] args) {

int sum = 0 ;//素数和

String s="";//素数

boolean y = true ;

for(int i = 100 ; i = 1000 ; i++){

y=true;//为每个数初始化y为真

for(int j = 2 ; j i ; j++){

if(i % j == 0){

y = false;//被除了1和本身以外的数整除为false

break;

}

}

if(y)

{

s+=i+" ";

sum+=i;

}

}

System.out.println("素数为:"+s);

System.out.println("素数和为:"+sum);

}

}

6--------------------------------------------------------------

public class Demo{

public static void main(String args[]){

int i,j;

for(i=1;i10;i++)

{

for(j=1;j=i;j++) //此处如果想输入完全的9x9则将j=i改为j10

{

System.out.print(j+"*"+i+"="+i*j+"\t");

}

System.out.println();

}

}

}
