Java-java 打印汉字码表

Question

想打印下汉字的码表,却不知道该如何实现了... 我这样写
for(char i=0x4e00;i<0x9fa5;i++) sysout( (char) i );

但是打印出来的有很多不可见字符,而且 0x9fa5 - 0x4e00 = 20901;单纯 汉字应该没有这么多...

求解 如何打印 中文汉字码表

Answer 1

public class Test {

public static void main(String[] args) {
int total = 0;
for (char i = 0x4e00; i <= 0x9fa5; i++) {
Character ch = new Character((char)i);
String v = ch.toString();
try {
byte[] b = v.getBytes("GB2312"); // 通过是否是 gb2312 编码来判断是否是简体中文
if (b.length > 1) {
// System.out.println(v);
total++;
}
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
System.out.println(total);
}
}

我没有验证是否是正确，这样出来的总数是 6763
