我以为是一道解法很丰富的题,选择了:把string转为int,用int的加法,再转为string返回。因为我讨厌用字符串来进位。但是溢出了。可以改进一下,用BigInteger这个类。 先贴上我的错误代码。 importjava.io.*;importjava.util.*;importjava.lang.*;publicclassSolution {publicstaticinttoInt(String s) {intlen=s.le...
static String hexToBin(String s) { return new BigInteger(s, 16).toString(2); } To ensure trouble-free conversion of large numbers,BigIntegercan be used. However, for a better understanding of conversion, you can also opt for the simpler code provided below. String hexToBinary(String hex) {...
equale(Object ); 传入一个包装类.进行比较. 方法跟compareTo类似.不过可以接受的参数都是. toString toBinaryString toHexString 返回包装类数值的字符表现形式. 以进制返回. 例如10进制16. 使用toHexString进行返回.那么数值就是0x10 Integer ValueOf(String str) ; 传入字符串数值.根据字符串数值.返回他的包装类....
