成都創(chuàng)新互聯(lián)網(wǎng)站制作重慶分公司

java編程代碼漢化,編程軟件漢化

懂JAVA 編程大師進(jìn)一下?。?!看代碼 怎么設(shè)置或者添加代碼能顯示中文

此問題可以通過FILTER來解決

成都創(chuàng)新互聯(lián)長(zhǎng)期為上千客戶提供的網(wǎng)站建設(shè)服務(wù),團(tuán)隊(duì)從業(yè)經(jīng)驗(yàn)10年,關(guān)注不同地域、不同群體,并針對(duì)不同對(duì)象提供差異化的產(chǎn)品和服務(wù);打造開放共贏平臺(tái),與合作伙伴共同營(yíng)造健康的互聯(lián)網(wǎng)生態(tài)環(huán)境。為湞江企業(yè)提供專業(yè)的成都網(wǎng)站建設(shè)、成都做網(wǎng)站,湞江網(wǎng)站改版等技術(shù)服務(wù)。擁有十載豐富建站經(jīng)驗(yàn)和眾多成功案例,為您定制開發(fā)。

public void init(FilterConfig config) throws ServletException

{

this.requestEncoding = config.getInitParameter("requestEncoding");

this.requestEncoding = ((this.requestEncoding == null) ? "utf-8" : this.requestEncoding);

this.responseEncoding = config.getInitParameter("responseEncoding");

}

頁(yè)面的編碼方式后臺(tái)需要處理,如果不想每一個(gè)頁(yè)面單獨(dú)處理可以配置一個(gè)filter將字符集更改下,中文問題就解決了

java編程的代碼

1.

public?class?Gun?{??????????//設(shè)置一個(gè)槍類

private?String?name;??????//槍名????

private?int?num;??????????//子彈的個(gè)數(shù)

private??int??Id;???//槍的Id

static?int?count;???????

public??Gun(){}

public?Gun(String?name,?int?num,?int?id)?{

this.name=name;

this.num=12;

}

public?Gun(String?name,int?num)?{

this.name=name;

this.num=num;

this.Id=count++;

}?

public?String?getName()?{

return?name;

}

public?void?setName(String?name)?{

this.name?=?name;

}

public?int?getNum()?{

return?num;

}

public?void?setNum(int?num)?{

this.num?=?num;

}

public??int?getId(){

return?Id;

}

public??void?setId(int?id)?{

Id?=?id;

}

public?void?fire(){???????//槍的發(fā)射方法

??

}

@Override

public?String?toString()?{????//覆寫toString?

return?"Gun?[name="?+?name?+?",?num="?+?num?+?",?Id="?+?Id?+?"]";

}??

}

public?class?Ak_47?extends?Gun?{

//構(gòu)造器的重載

public?Ak_47(){}???????//構(gòu)造器

public?Ak_47(String?name,int?num){???

super(name,num);

}

public??void?fire(){?????//發(fā)射子彈?????,每次射出3發(fā)

???super.setNum(super.getNum()-3);??//得到子彈的數(shù)目???

}

public?void??clip(){????//裝彈夾???每個(gè)彈夾30發(fā)子彈

???super.setNum(super.getNum()+30);???

}

public?String?toString(){?????//toString的重寫

???return?"槍名:"+super.getName()+"\t"+"編號(hào):"+super.getId()+"\t"+"子彈數(shù):"+super.getNum();

}

}

public?class?Usp?extends?Gun?{

public?Usp(){}

public?Usp(String?name,int?num){???

super(name,num);

}

?public??void?fire(){?????//發(fā)射子彈?,每次發(fā)射一發(fā)

???super.setNum(super.getNum()-1);??//得到子彈的數(shù)目???

???}

???public?void??clip(){????//裝彈夾

???super.setNum(super.getNum()+12);???

???}

???public?String?toString(){

???return?"槍名:"+super.getName()+"\t"+"編號(hào):"+super.getId()+"\t"+"子彈數(shù):"+super.getNum();

???}

}

public?class?GunTest?{

public?static?void?main(String[]?args)?{

Ak_47?ak=new?Ak_47("ak",20);//Ak-47的彈夾可以裝30子彈

Ak_47?bk=new?Ak_47("us",12);

ak.fire();

bk.fire();

ak.clip();

bk.clip();

System.out.println(ak);

System.out.println(bk);

}

}

可以了

急?。?!簡(jiǎn)單JAVA編程代碼

public class Test {

public static void main(String[] args) {

MyRectangle rec = new MyRectangle(3, 5);

MyRectangle square = new MySquare(4);

System.out.println(rec.toString());

System.out.println(square.toString());

}

}

class MyRectangle{

protected double width;

protected double length;

public MyRectangle(double length, double width){

this.width = width;

this.length = length;

}

public double getLength() {

return length;

}

public double getWidth() {

return width;

}

public void setWidth(double width) {

this.width = width;

}

public double getArea(){

return this.width * this.length;

}

public String toString(){

return "長(zhǎng)方形的長(zhǎng)為:" + length + ", 寬: " + width + ", 面積為:" + getArea();

}

}

class MySquare extends MyRectangle{

public MySquare(double length){

super(length, length);

}

public double getArea(){

return Math.pow(super.width, 2);

}

public String toString(){

return "正方形邊長(zhǎng)為: " + super.length + ", 面積為: " + getArea();

}

}

----------測(cè)試

長(zhǎng)方形的長(zhǎng)為:3.0, 寬: 5.0, 面積為:15.0

正方形邊長(zhǎng)為: 4.0, 面積為: 16.0

Java編程 代碼如下

"13423"

foo(0) 時(shí) output 值為"134"

foo(1) 詩(shī) output 值為"13423"

因?yàn)閒inally無論出沒出現(xiàn)異常都會(huì)要執(zhí)行的,哪怕你寫了return。所以finally語(yǔ)句塊常用來“收尾”工作。

Java編程(寫出程序代碼)

import?java.util.Scanner;

/*輸入一個(gè)成績(jī),將該成績(jī)轉(zhuǎn)換為A、B、C、D和E:成績(jī)?cè)?0分以上,結(jié)果為A,成績(jī)?cè)?0-90之間,結(jié)果為B,成績(jī)?cè)?0-80之間,結(jié)果為C,成績(jī)?cè)?0-70之間,結(jié)果為D,成績(jī)?cè)?0分以下,結(jié)果為E。*/

public?class?Chengfabiao

{

public?static?void?main?(String[]?args)

{

Scanner?scanner?=?new?Scanner(System.in);

int?score?=?scanner.nextInt();

if(score90)

{

System.out.println("A");

}

else?if(score=80)

{

System.out.println("B");

}

else?if(score=70)

{

System.out.println("C");

}

else?if(score=60)

{

System.out.println("D");

}

else

{

System.out.println("E");

}

}

}

求JAVA編程代碼

答案放在下面地址:

順便給我踩下空間^-^

本小牛聽了那六級(jí)大牛的建議后做了如下修改

第1題:

import java.awt.*;

import java.awt.event.*;

import java.applet.*;

public class wangquanshu extends Applet implements ActionListener

{

int aa[]={6,28,496,8128,130816,2096128,33550336},bb[]={0,0,0,0,0,0,0};

//6=1+2+3

//28=1+2+4+7+14

//496=1+2+4+8+16+31+62+124+248

//8128=1+2+4+8+16+32+64+127+254+508+1016+2032+4064

//在1到40000000這么多數(shù)里,只有七個(gè)完全數(shù),它們是:6,28,496,8128,130816,2096128,33550336

//java里int 32位 -2^31~2^31-1(大概20億,應(yīng)夠了)

int j,q;

Label lab1;

TextField text1;

Label lab2;

TextField text2;

Button but;

public void init()

{ lab1=new Label("請(qǐng)輸入上下限:");

text1=new TextField(8);

lab2=new Label(" - ");

text2=new TextField(8);

but=new Button("確定");

add(lab1);

add(text1);

add(lab2);

add(text2);

add(but);

but.addActionListener(this);

}

public void paint(Graphics g)

{int m=1; //用于控制輸出自由數(shù)的位置

for(int n=0;n7;n++)

{g.drawString(" "+bb[n],10,50+m*20);

m++;

}

}

public void actionPerformed(ActionEvent e)

{int s=0;

int a=Integer.parseInt(text1.getText());

int b=Integer.parseInt(text2.getText());

for(j=0;j7;j++)

{if(aa[j]aaa[j]b)

bb[j]=aa[j];

}

repaint();

}

}

第2題:

import java.io.*;

import java.text.DecimalFormat;

public class e

{public static void main(String args[])

{double ee=0;

for(int i=0;i=11;i++)

{ee=ee+1/re(i);

}

DecimalFormat a=new DecimalFormat("0.00000000");

System.out.println(a.format(ee));

}

static double re(int n)

{if(n==0||n==1) return 1;

else return n*re(n-1);

}

}
