java大神来！很急
public class Test1 {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("请输入一组字符，长度不超过1000：");
while (true) {
String str = sc.nextLine();
if ("#".equals(str)) {
System.exit(0);
}
if (str.length() 1000) {
str.substring(0, 1001);
}
StringBuilder sb = new StringBuilder(str);
StringBuilder sbNew = new StringBuilder();
for (int i = 0; i sb.length(); i++) {
sbNew.append(change(sb.charAt(i)));
}
System.out.println(sbNew.toString());
}
}
public static String change(char a) {
switch (a) {
case ' ':
return "%20";
case '!':
return "%21";
case '$':
return "%24";
case '%':
return "%25";
case '(':
return "%28";
case ')':
return "%29";
case '*':
return "%2a";
default:
return "" + a;
}
}
}
Java：如何打印出这种详细的Get、Post请求信息呢？
看你提供的信息，应该是数据流监控到的。
像插件或者工具提供的信息，也是这个插件和工具开发人员设计的信息。
原理一样，都是程序员开发出来的，如果你要在你的java中实现，需要你自己去开发。比较代码可不是只能的，所有的一切都是你设计出来的。java通常的做法是记录log日志。
java中byteValue 怎么用啊?
byte b=a.byteValue(); X
貌似你要把a里的值经过强制类型转换后放进b里。
首先强制类型转换的写法是byte b = (byte)a;
其次，即使改成这样写也是会报错的，
因为byte类型不能接受大于128的值。
所以你的想法不能实现。
点在图片上 显示日历框 可以选择日历上的日期 来查询对应时间数据库的信息 这个JSP代码怎么写

怎样做到在windows界面下修改BIOS设置
无法做到在windows界面下修改BIOS设置，会冲突的。
一般各种主板进入bios设置都是不一样，当然我们在开机的时候仔细看就会看到提示进入bios的功能键。电脑开机显示：
1、Award BIOS：按“Del”键
2、AMI BIOS：按“Del”或“ESC”键
3、Phoenix BIOS：按“F2”键
各路品牌电脑进入bios设置：
1、IBMToshiba：冷开机按F1，部分新型号可以在重新启动时启动按F1
2、Compaq：开机到右上角出现闪动光标时按F10，或者开机时按F10
3、Toshiba：冷开机时按ESC然后按F1
4、HP惠普、SONY索尼、Dell戴尔、Acer、Fujitsu、绝大多数国产和台湾品牌：启动和重新启动时按F2。
求简洁的java代码。输入五个数，比较后输出最大值和最小值，用java语言编写
Scanner input = new Scanner( System.in );
int number1;
int number2;
int number3;
int number4;
int number5;
System.out.print( "Enter first integer: " );
number1 = input.nextInt();
System.out.print( "Enter second integer: " );
number2 = input.nextInt();
System.out.print( "Enter third integer: " );
number3 = input.nextInt();
System.out.print( "Enter fourth integer: " );
number4 = input.nextInt();
System.out.print( "Enter fifth integer: " );
number5 = input.nextInt();
int[] a = new int[5];
a[0] = number1;
a[1] = number2;
a[2] = number3;
a[3] = number4;
a[4] = number5;
int min = 999;
int max = 0;
for (int i = 0; i 5; i++) {
if (a[i] min) {
min = a[i];
}
}
for (int i = 0; i 5; i++) {
if (a[i] max) {
max = a[i];
}
}
System.out.println("最小：" + min + " 最大：" + max);
