Java编程求代码

这个是需要用JAVASCRIPT或者JQUERY 解决吧，这属于JSP的问题吧。

思路 ：如果是JQUERY 需要定义一个function 方法名（参数）将按钮A绑定一个双击事件 （参数是A或者是其对应的ascii码 65）如果参数是大写的A 则需要在方法体内将其转成 对应ascii码。具体复制的实现 ：如果A按钮 input type="button" id = "a"在一个DIV内 如div id ="div"

input type="button" id = "a"A/input

/div

只需要 获取当前ID为div的div$("#div") 之后再起后边加入通过append方法在A的后边加入按钮B（A+1）(所以首先应该将传入的参数65 加1获取其下一个字母) 。具体实现$("#div")

.append(input type="button" 双击事件="方法名(新获得的字母)"新获得的字母/input);取消参数按钮绑定 给新获得的字母绑定双击事件。

一道Java编程题 求源代码

public class Invoice {

String bianhao = null;

String shuoming = null;

int count = 0;

double price = 0.0;

public Invoice(String bianhao, String shuoming, int count, double price) {

this.bianhao = bianhao;

this.shuoming = shuoming;

if (count 0) {

this.count = 0;

} else {

this.count = count;

}

if (price 0.0) {

this.price = 0.0;

} else {

this.price = price;

}

}

public double getInvoiceAmount() {

return count * price;

}

public String getBianhao() {

return bianhao;

}

public void setBianhao(String bianhao) {

this.bianhao = bianhao;

}

public int getCount() {

return count;

}

public void setCount(int count) {

this.count = count;

}

public double getPrice() {

return price;

}

public void setPrice(double price) {

this.price = price;

}

public String getShuoming() {

return shuoming;

}

public void setShuoming(String shuoming) {

this.shuoming = shuoming;

}

}

public class InvoiceTest {

/**

* @param args

*/

public static void main(String[] args) {

Invoice invoice = new Invoice("010220", "Desk", 50, 53.9);

System.out.println(invoice.getInvoiceAmount());

}

}

JAVA编程

这个应该不是在运行时提示, 应该编译器就会提示, 因为你写的三个方法都是非静态的, 而你的main方法 静态的, 所以你无法直接在main方法中调用那个三个字符串处理方法, 你要先实例化一个Strinput的对象然后通过这个对象调用那三个方法

java编程代码!请仔细看我的说明. . .
