我正在尝试将字符串转换为Long / Int并保持获取NumberFormatException。字符串是我不明白的数字。我试图解析为两倍并得到无限。 我在做什么错了？
public class EncryptDecrypt {
private char[] localKey;
private long keyNumber;
public EncryptDecrypt(char[] localKey) {
this.localKey = localKey; // Brings in 256 random characters
keyNumber = makeKeyNumber(localKey);
System.out.println(keyNumber); //prints long
}
private long makeKeyNumber(char[] key) {
StringBuilder keyString = new StringBuilder();
for(int i = 0; i<key.length; i++) { //Builds String from chatacter array
int ascii = (int) key[i];
keyString.append(ascii);
}
String s = keyString.toString(); // Makes a string from stringbuilder
long keyNum = Long.parseLong(s); // Attempts to convert string to long
return keyNum; //returns long
}
}
错误
Exception in thread "main" java.lang.NumberFormatException: For input string: "1121214840113493593108124959933124991191111155510211549117935560351251051181216112311811354631064111712563371141044610510739101436457101108361109395411095555121465711133107466391125103119411219910436575950469549424363114114614597491064011312110398491254136371199942110115985141102122464410410060611086111311011210811242123981091054612045104911091191231131164345115124991245638913543123394658985539123112117113421225444351169157529911549435933949598434157591021241194249113425311535454957111108107611074064113944040601001145036333610510548933848994911550118593511910712163581141209743101643361100113999954931191246395107"
