JAVA 字符串有中文可以转换为int类吗？

JAVA 字符串有中文可以转换为int类吗？

public class var07{
public static void main(String[]args){
String s1 = "东";
int num1 =Integer.parseInt(s1);
System.out.println(num1);
}
}

然后就报错为

Exception in thread "main" java.lang.NumberFormatException: For input string: "东"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
at java.lang.Integer.parseInt(Integer.java:580)
at java.lang.Integer.parseInt(Integer.java:615)
at var07.main(var07.java:4)

是语法出现什么错误了吗？求解答过程

这种字符串不可能转换成int

中文怎么可能转换为数字啊
这个只能转换字符串中的数字，比如String s1 = "123"这样的

东应该被转成数字多少

public static int parseInt(String s, int radix)
            throws NumberFormatException
{
    /*
     * WARNING: This method may be invoked early during VM initialization
     * before IntegerCache is initialized. Care must be taken to not use
     * the valueOf method.
     */
    if (s == null) {
        // Android-changed: Improve exception message for parseInt.
        throw new NumberFormatException("s == null");
    }
    if (radix < Character.MIN_RADIX) {
        throw new NumberFormatException("radix " + radix +
                                        " less than Character.MIN_RADIX");
    }
    if (radix > Character.MAX_RADIX) {
        throw new NumberFormatException("radix " + radix +
                                        " greater than Character.MAX_RADIX");
    }
    int result = 0;
    boolean negative = false;
    int i = 0, len = s.length();
    int limit = -Integer.MAX_VALUE;
    int multmin;
    int digit;
    if (len > 0) {
        char firstChar = s.charAt(0);
        if (firstChar < '0') { // Possible leading "+" or "-"
            if (firstChar == '-') {
                negative = true;
                limit = Integer.MIN_VALUE;
            } else if (firstChar != '+')
                throw NumberFormatException.forInputString(s);
            if (len == 1) // Cannot have lone "+" or "-"
                throw NumberFormatException.forInputString(s);
            i++;
        }
        multmin = limit / radix;
        while (i < len) {
            // Accumulating negatively avoids surprises near MAX_VALUE
            digit = Character.digit(s.charAt(i++),radix);
            if (digit < 0) {
                throw NumberFormatException.forInputString(s);
            }
            if (result < multmin) {
                throw NumberFormatException.forInputString(s);
            }
            result *= radix;
            if (result < limit + digit) {
                throw NumberFormatException.forInputString(s);
            }
            result -= digit;
        }
    } else {
        throw NumberFormatException.forInputString(s);
    }
    return negative ? result : -result;
}

转int是通过ascii得到的，汉字的ascii值很大的

public class var07{
public static void main(String[]args){
String s1 = "东";
System.out.println(s1.charAt(0)+0);
}
}

建议你看下这篇博客java中Int类型数字转中文

不能哦，字符串中必须全部是数字才可以

那怎么转？一个中文你想让它转成什么数字？

只有纯数字的字符串，才能被转成int型
