java編程的思路

java基本編程思路：

成都創(chuàng)新互聯(lián)公司，專(zhuān)注為中小企業(yè)提供官網(wǎng)建設(shè)、營(yíng)銷(xiāo)型網(wǎng)站制作、成都響應(yīng)式網(wǎng)站建設(shè)、展示型成都網(wǎng)站制作、成都做網(wǎng)站等服務(wù)，幫助中小企業(yè)通過(guò)網(wǎng)站體現(xiàn)價(jià)值、有效益。幫助企業(yè)快速建站、解決網(wǎng)站建設(shè)與網(wǎng)站營(yíng)銷(xiāo)推廣問(wèn)題。

第一步：寫(xiě)框架(內(nèi)層和外層)：

public class?類(lèi)名{//外層

public static void main(String[ ] args){//內(nèi)層

}

}

第二步：看題目中是否有“接收”“輸入”“錄入”等字眼，則導(dǎo)入util包，創(chuàng)建Scanner掃描儀對(duì)象：

import??java.util.Scanner；//寫(xiě)在文件的第一行

Scanner??input = new Scanner(System.in)；//寫(xiě)在main方法中的第一行

第三步：編寫(xiě)main方法中的主體代碼

A、接收、輸入、錄入：

System.out.println(“提示信息”);

數(shù)據(jù)類(lèi)型??變量名=__掃描數(shù)據(jù)___；

說(shuō)明：掃描不同類(lèi)型的數(shù)據(jù)，使用不同的掃描方法。以下介紹了常用的類(lèi)型的掃描方法。

int型?????使用nextInt();

String型?????使用next ()或nextLine();

double型??????使用nextDouble();

B、計(jì)算：算術(shù)運(yùn)算等

C、輸出：

System.out.println(輸出的內(nèi)容);

或者

System.out.println(“提示內(nèi)容：”+輸出的內(nèi)容);

這是我們課本上的，顏色不一樣，其他的都差不多，不過(guò)是用awt組件寫(xiě)的，你應(yīng)該是要用swing寫(xiě)的吧，照這個(gè)改改吧...
