當一個字符串常量過長時，可以采取以下幾種解決方案：
String longStr = "This is a very long string that needs to be split into multiple shorter strings for better readability."
String shortStr = "This is a very long string" + " that needs to be split" + " into multiple shorter strings" + " for better readability.";
String[] strParts = {"This is a very long string", " that needs to be split", " into multiple shorter strings", " for better readability."};
String shortStr = String.join("", strParts);
String fileName = "longString.txt";
String longStr = "";
try {
BufferedReader reader = new BufferedReader(new FileReader(fileName));
String line;
while ((line = reader.readLine()) != null) {
longStr += line;
}
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
以上是常見的解決方案，具體使用哪種方法取決于實際需求和代碼的可讀性要求。
