public static void main(String[] args) {
// 定义数组
int[][] array = new int[5][6];
// 生成随机数初始化数组
for (int i = 0; i array.length; i++) {
for (int j = 0; j array[i].length; j++) {
array[i][j] = (int) (40 * Math.random()) + 10;
}
}
// 输出数组
for (int i = 0; i array.length; i++) {
for (int j = 0; j array[i].length; j++) {
System.out.print(array[i][j] + "\t");
}
System.out.println(); // 换行
}
}
}
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
