Question

在JAVA输入一个数字 输出他在Unicode表中对应的字符

怎样实现？
下面这段代码为什么不对
import java.util.*;
public class S{
public static void main (String args[]){
Scanner rd=new Scanner(System.in);
int s=rd.NextInt();
char a;
a=s;
System.out.println(a);
}
}

Answer 1

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class UnicodeDemo {

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

//String s="sdjakjdkl";
//键盘录入
while(true)
{
BufferedReader bufr = new BufferedReader(new InputStreamReader(System.in));
String s=bufr.readLine();//.toString();
if("over".equals(s)){
break;
}
String u=string2Unicode(s);
System.out.println(u);
}

}

public static String string2Unicode(String string) {

StringBuffer unicode = new StringBuffer();

for (int i = 0; i < string.length(); i++) {

// 取出每一个字符
char c = string.charAt(i);

// 转换为unicode
unicode.append("\\u" + Integer.toHexString(c));
}

return unicode.toString();
}
}
