java中产生随机汉字

[hyb2008dxy]

java中如何产生一个随机的汉字，不用预存在数组的方式来做的话，有没有其他方法？

[allenblade]

可以考虑使用unicode码

[allenblade]

4e00-9fa5编码范围，这个范围里应该都是中文。。。

[hyb2008dxy]

能不能给出实际代码？

答：参考代码如下：

//在0x4e00---0x9fa5之间产生一个随机的字符
	public static char getRandomChar()
	{		
		return (char)(0x4e00+(int)(Math.random()*(0x9fa5-0x4e00+1)));
	}

晕，4位16进制随机数阿。。。范围就是上面得

给LZ写了一个,不晓得要得不?
import java.util.Date;
import java.util.Random;

public class Chinese {
public String getChinese(long seed) throws Exception {
String str = null;
int highPos, lowPos;
seed = new Date().getTime();
Random random = new Random(seed);
highPos = (176 + Math.abs(random.nextInt(39)));
lowPos = 161 + Math.abs(random.nextInt(93));
byte[] b = new byte[2];
b[0] = (new Integer(highPos)).byteValue();
b[1] = (new Integer(lowPos)).byteValue();
str = new String(b, "GB2312");
return str;
}

public static String get300Chinese() throws Exception {
Chinese ch = new Chinese();
String str = "";
for (int i = 300; i > 0; i--) {
str = str + ch.getChinese(i);

}
System.out.println(str);
return str;
}

public static void main(String[] args) throws Exception {

get300Chinese();
}
}

public class Test1 {
    public static void main(String[] args) {
        RandomHan han = new RandomHan();
        System.out.println(han.getRandomHan());
    }
}

class RandomHan {
    private Random ran = new Random();
    private final static int delta = 0x9fa5 - 0x4e00 + 1;
    
    public char getRandomHan() {
        return (char)(0x4e00 + ran.nextInt(delta)); 
    }
}

是不是无论在Ｃ或者ＪＡＶＡ中定义一个随机函数之前都要先设置好种子seed??

[jpinglove]

晕,都是牛人,这些代码,我也收藏了!

[wyhlgx]

不行，这些汉字很多不认识。有的是繁体的。
