簡單java論壇源碼

㈠ java小程序源代碼，簡單點的，100多行，誰有啊

java小程序只是把java語言嵌套在html中，只要你會html那麼你就按照html的寫法標准寫就行了啊！

㈡ 求編寫一個超級簡單的Java的程序源代碼

你自己慢慢的看吧！

㈢ GitHub上面有哪些經典的java框架源碼

㈣ 誰有java開發的簡單網站源碼，要求簡單的增刪改除，不用框架，最好是servlet+jsp +mysql實現,畢設要用

JSP沒有免費的，不然你也不在這里來問別人了吧。JSP資源很少，不是ASP.PHP，源碼很多，什麼樣的都有。可以定做，速度快。

㈤ 高分求兩個簡單的JAVA設計源代碼

我寫的是第一題，不知道行不行。
代碼寫在一個Java文件中：

import java.util.*;

public class Student implements Comparator
{
private String stuNo; //學號
private String name; //姓名
private double engScore; //英語成績
private double mathScore; //數學成績
private double comScore; //計算機成績
private double sum; //總成績

//計算評測成績
public double testScore(){
return (this.getEngScore()+this.getMathScore()+this.getComScore())/3;
}
//計算總成績
public double sum(){
return this.getEngScore()+this.getMathScore()+this.getComScore();
}
//實現compare方法
public int compare(Object object1,Object object2){
Student student1 = (Student)object1;
Student student2 = (Student)object2;

return student1.getSum() > student2.getSum() ? 1 : student1.getSum() < student2.getSum() ? -1 : 0 ;
}
//重寫toString方法
public String toString(){
return "學號："+this.getStuNo()+" 姓名："+this.getName()+" 英語成績："+this.getEngScore()+" 數學成績："+this.getMathScore()+" 計算機成績："+this.getComScore()+" 總成績："+this.getSum();
}

//重寫equals方法
public boolean equals(Object object){
if(object == null){
return false;
}
if(!(object instanceof Student)){
return false;
}
Student student = (Student)object;
if(student.getStuNo().equals(this.getStuNo()) && student.getName().equals(this.getName()) && student.getEngScore() == this.getEngScore() && student.getMathScore() == this.getMathScore() && student.getComScore() == this.getComScore() && student.getSum() == this.getSum()){
return true;
}
return true;
}
//getter和setter方法
public void setStuNo(String stuNo){
this.stuNo = stuNo;
}
public void setName(String name){
this.name = name;
}
public void setEngScore(double engScore){
this.engScore = engScore;
this.sum = this.sum();
}
public void setMathScore(double mathScore){
this.mathScore = mathScore;
this.sum = this.sum();
}
public void setComScore(double comScore){
this.comScore = comScore;
this.sum = this.sum();
}
public void setSum(double sum){
this.sum = sum;
}

public String getStuNo(){
return stuNo;
}
public String getName(){
return name;
}
public double getEngScore(){
return engScore;
}
public double getMathScore(){
return mathScore;
}
public double getComScore(){
return comScore;
}
public double getSum(){
return sum;
}

//無參構造方法
public Student(){}
//有參構造方法
public Student(String stuNo,String name,double engScore,double mathScore,double comScore){
this.stuNo = stuNo;
this.name = name;
this.engScore = engScore;
this.mathScore = mathScore;
this.comScore = comScore;
}
public Student(String stuNo,String name,double engScore,double mathScore,double comScore,double sum){
this(stuNo,name,engScore,mathScore,comScore);
this.sum = sum;
}
}

//班長子類
class StudentBZ extends Student
{
private String ty;//責任

public StudentBZ(){}
public StudentBZ(String stuNo,String name,double engScore,double mathScore,double comScore){
super(stuNo,name,engScore,mathScore,comScore);
}
public StudentBZ(String stuNo,String name,double engScore,double mathScore,double comScore,double sum){
super(stuNo,name,engScore,mathScore,comScore,sum);
}

public String getDuty(){
return ty;
}
public void setDuty(String ty){
this.ty = ty;
}
//重寫testScore方法
public double testScore(){
return (this.getEngScore()+this.getMathScore()+this.getComScore())/3 + 5;
}
}

//學委子類
class StudentXW extends Student
{
private String ty;//責任

public String getDuty(){
return ty;
}
public void setDuty(String ty){
this.ty = ty;
}

public StudentXW(String stuNo,String name,double engScore,double mathScore,double comScore){
super(stuNo,name,engScore,mathScore,comScore);
}
public StudentXW(String stuNo,String name,double engScore,double mathScore,double comScore,double sum){
super(stuNo,name,engScore,mathScore,comScore,sum);
}
//重寫testScore方法
public double testScore(){
return (this.getEngScore()+this.getMathScore()+this.getComScore())/3 + 3;
}
}

//測試類
class Test
{
public static void main(String[] args){
//Student(String stuNo,String name,double engScore,double mathScore,double comScore,double sum)
//生成若干個student類、StudentXW類、StudentBZ類
Student student1 = new Student("s001","張三",70.5,50,88.5);
Student student2 = new Student("s002","李四",88,65,88.5);
Student student3 = new Student("s003","王五",67,77,90);
StudentXW student4 = new StudentXW("s004","李六",99,88,99.5);
StudentBZ student5 = new StudentBZ("s005","朱漆",56,65.6,43.5);

Student[] students = {student1,student2,student3,student4,student5};

for(int i = 0 ; i<students.length; i++){
double avgScore = students[i].testScore();
System.out.println("第"+(i+1)+"個學生的評測成績為："+ avgScore+"分");
}
}
}

㈥ 求幾個JAVA小項目源代碼，供自己學習參考

package com.test01;
import java.util.Scanner;
public class oop5 { public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
// int x = 9;
// int y = 1;
int x = sc.nextInt();
int y = sc.nextInt();
int z;
z = add(x, y);
System.out.println("x的值為：" + x);
System.out.println("y的值為：" + y);
System.out.println("二者之和為：" + z);
}

/** 四種小演算法 */
// 加法運算
public static int add(int a, int b) {
int c;
c = a + b;
return c;
}

// 減法運算
public static int jian(int d, int v) {
int m;
m = d - v;
return m;
}

// 乘積運算
public static int addAdd(int q, int w) {
int e;
e = q * w;
return e;
}

// 除法運算
public static int chu(int p, int k) {
int f;
f = p / k;
return f;
}
}

㈦ java論壇

CSDN吧，那裡是大牛聚集的地方，有不懂的都可以在那提問。

CSDN是中國軟體開發聯盟（Chinese software develop net）的縮寫，是中國最大的開發者技術社區。它是集新聞、論壇、群組、Blog、文檔、下載、讀書、Tag、網摘、搜索、.NET、Java、游戲、視頻、人才、外包、第二書店、《程序員》等多種項目於一體的大型綜合性IT門戶網站，有很強的專業性，其會員囊括了中國地區百分之九十以上的優秀程序員，在IT技術交流及其周邊國內中是第一位的網站。

滿意請採納，謝謝啦。

㈧ java論壇源碼哪裡可以下載提供幾個好的源碼下載站！謝謝

樓上的那個javaEye 論壇是不錯，不過比較適合學到了Java EE再去。

建議你去www.csdn.net，比較適合很多編程語言初級應用的網站，資源也超級豐富。

㈨ 正在學習java, 有哪些比較好的java源代碼論壇或者開源項目網站(...

w3school、http://www.runoob.com/jsref/dom-obj-document.html

㈩ 求一個簡單java程序代碼，謝謝

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 但是我沒找到畫五角星有什麼規律（五角星好象不是正規圖形吧？）如果還有什麼要求的話 補充問題(如果是用*填充所有的東西 不包括 「 」的話 我可以重新再給你寫一個)
